+# Animations
+
+Use Reanimated v4. Avoid React Native's built-in Animated API.
+
+## Entering and Exiting Animations
+
+Use Animated.View with entering and exiting animations. Layout animations can animate state changes.
+
+```tsx
+import Animated, {
+  FadeIn,
+  FadeOut,
+  LinearTransition,
+} from "react-native-reanimated";
+
+function App() {
+  return (
+    <Animated.View
+      entering={FadeIn}
+      exiting={FadeOut}
+      layout={LinearTransition}
+    />
+  );
+}
+```
+
+## On-Scroll Animations
+
+Create high-performance scroll animations using Reanimated's hooks:
+
+```tsx
+import Animated, {
+  useAnimatedRef,
+  useScrollViewOffset,
+  useAnimatedStyle,
+  interpolate,
+} from "react-native-reanimated";
+
+function Page() {
+  const ref = useAnimatedRef();
+  const scroll = useScrollViewOffset(ref);
+
+  const style = useAnimatedStyle(() => ({
+    opacity: interpolate(scroll.value, [0, 30], [0, 1], "clamp"),
+  }));
+
+  return (
+    <Animated.ScrollView ref={ref}>
+      <Animated.View style={style} />
+    </Animated.ScrollView>
+  );
+}
+```
+
+## Common Animation Presets
+
+### Entering Animations
+
+- `FadeIn`, `FadeInUp`, `FadeInDown`, `FadeInLeft`, `FadeInRight`
+- `SlideInUp`, `SlideInDown`, `SlideInLeft`, `SlideInRight`
+- `ZoomIn`, `ZoomInUp`, `ZoomInDown`
+- `BounceIn`, `BounceInUp`, `BounceInDown`
+
+### Exiting Animations
+
+- `FadeOut`, `FadeOutUp`, `FadeOutDown`, `FadeOutLeft`, `FadeOutRight`
+- `SlideOutUp`, `SlideOutDown`, `SlideOutLeft`, `SlideOutRight`
+- `ZoomOut`, `ZoomOutUp`, `ZoomOutDown`
+- `BounceOut`, `BounceOutUp`, `BounceOutDown`
+
+### Layout Animations
+
+- `LinearTransition` — Smooth linear interpolation
+- `SequencedTransition` — Sequenced property changes
+- `FadingTransition` — Fade between states
+
+## Customizing Animations
+
+```tsx
+<Animated.View
+  entering={FadeInDown.duration(500).delay(200)}
+  exiting={FadeOut.duration(300)}
+/>
+```
+
+### Modifiers
+
+```tsx
+// Duration in milliseconds
+FadeIn.duration(300);
+
+// Delay before starting
+FadeIn.delay(100);
+
+// Spring physics
+FadeIn.springify();
+FadeIn.springify().damping(15).stiffness(100);
+
+// Easing curves
+FadeIn.easing(Easing.bezier(0.25, 0.1, 0.25, 1));
+
+// Chaining
+FadeInDown.duration(400).delay(200).springify();
+```
+
+## Shared Value Animations
+
+For imperative control over animations:
+
+```tsx
+import {
+  useSharedValue,
+  withSpring,
+  withTiming,
+} from "react-native-reanimated";
+
+const offset = useSharedValue(0);
+
+// Spring animation
+offset.value = withSpring(100);
+
+// Timing animation
+offset.value = withTiming(100, { duration: 300 });
+
+// Use in styles
+const style = useAnimatedStyle(() => ({
+  transform: [{ translateX: offset.value }],
+}));
+```
+
+## Gesture Animations
+
+Combine with React Native Gesture Handler:
+
+```tsx
+import { Gesture, GestureDetector } from "react-native-gesture-handler";
+import Animated, {
+  useSharedValue,
+  useAnimatedStyle,
+  withSpring,
+} from "react-native-reanimated";
+
+function DraggableBox() {
+  const translateX = useSharedValue(0);
+  const translateY = useSharedValue(0);
+
+  const gesture = Gesture.Pan()
+    .onUpdate((e) => {
+      translateX.value = e.translationX;
+      translateY.value = e.translationY;
+    })
+    .onEnd(() => {
+      translateX.value = withSpring(0);
+      translateY.value = withSpring(0);
+    });
+
+  const style = useAnimatedStyle(() => ({
+    transform: [
+      { translateX: translateX.value },
+      { translateY: translateY.value },
+    ],
+  }));
+
+  return (
+    <GestureDetector gesture={gesture}>
+      <Animated.View style={[styles.box, style]} />
+    </GestureDetector>
+  );
+}
+```
+
+## Keyboard Animations
+
+Animate with keyboard height changes:
+
+```tsx
+import Animated, {
+  useAnimatedKeyboard,
+  useAnimatedStyle,
+} from "react-native-reanimated";
+
+function KeyboardAwareView() {
+  const keyboard = useAnimatedKeyboard();
+
+  const style = useAnimatedStyle(() => ({
+    paddingBottom: keyboard.height.value,
+  }));
+
+  return <Animated.View style={style}>{/* content */}</Animated.View>;
+}
+```
+
+## Staggered List Animations
+
+Animate list items with delays:
+
+```tsx
+{
+  items.map((item, index) => (
+    <Animated.View
+      key={item.id}
+      entering={FadeInUp.delay(index * 50)}
+      exiting={FadeOutUp}
+    >
+      <ListItem item={item} />
+    </Animated.View>
+  ));
+}
+```
+
+## Best Practices
+
+- Add entering and exiting animations for state changes
+- Use layout animations when items are added/removed from lists
+- Use `useAnimatedStyle` for scroll-driven animations
+- Prefer `interpolate` with "clamp" for bounded values
+- You can't pass PlatformColors to reanimated views or styles; use static colors instead
+- Keep animations under 300ms for responsive feel
+- Use spring animations for natural movement
+- Avoid animating layout properties (width, height) when possible — prefer transforms

+# Native Controls
+
+Native iOS controls provide built-in haptics, accessibility, and platform-appropriate styling.
+
+## Switch
+
+Use for binary on/off settings. Has built-in haptics.
+
+```tsx
+import { Switch } from "react-native";
+import { useState } from "react";
+
+const [enabled, setEnabled] = useState(false);
+
+<Switch value={enabled} onValueChange={setEnabled} />;
+```
+
+### Customization
+
+```tsx
+<Switch
+  value={enabled}
+  onValueChange={setEnabled}
+  trackColor={{ false: "#767577", true: "#81b0ff" }}
+  thumbColor={enabled ? "#f5dd4b" : "#f4f3f4"}
+  ios_backgroundColor="#3e3e3e"
+/>
+```
+
+## Segmented Control
+
+Use for non-navigational tabs or mode selection. Avoid changing default colors.
+
+```tsx
+import SegmentedControl from "@react-native-segmented-control/segmented-control";
+import { useState } from "react";
+
+const [index, setIndex] = useState(0);
+
+<SegmentedControl
+  values={["All", "Active", "Done"]}
+  selectedIndex={index}
+  onChange={({ nativeEvent }) => setIndex(nativeEvent.selectedSegmentIndex)}
+/>;
+```
+
+### Rules
+
+- Maximum 4 options — use a picker for more
+- Keep labels short (1-2 words)
+- Avoid custom colors — native styling adapts to dark mode
+
+### With Icons (iOS 14+)
+
+```tsx
+<SegmentedControl
+  values={[
+    { label: "List", icon: "list.bullet" },
+    { label: "Grid", icon: "square.grid.2x2" },
+  ]}
+  selectedIndex={index}
+  onChange={({ nativeEvent }) => setIndex(nativeEvent.selectedSegmentIndex)}
+/>
+```
+
+## Slider
+
+Continuous value selection.
+
+```tsx
+import Slider from "@react-native-community/slider";
+import { useState } from "react";
+
+const [value, setValue] = useState(0.5);
+
+<Slider
+  value={value}
+  onValueChange={setValue}
+  minimumValue={0}
+  maximumValue={1}
+/>;
+```
+
+### Customization
+
+```tsx
+<Slider
+  value={value}
+  onValueChange={setValue}
+  minimumValue={0}
+  maximumValue={100}
+  step={1}
+  minimumTrackTintColor="#007AFF"
+  maximumTrackTintColor="#E5E5EA"
+  thumbTintColor="#007AFF"
+/>
+```
+
+### Discrete Steps
+
+```tsx
+<Slider
+  value={value}
+  onValueChange={setValue}
+  minimumValue={0}
+  maximumValue={10}
+  step={1}
+/>
+```
+
+## Date/Time Picker
+
+Compact pickers with popovers. Has built-in haptics.
+
+```tsx
+import DateTimePicker from "@react-native-community/datetimepicker";
+import { useState } from "react";
+
+const [date, setDate] = useState(new Date());
+
+<DateTimePicker
+  value={date}
+  onChange={(event, selectedDate) => {
+    if (selectedDate) setDate(selectedDate);
+  }}
+  mode="datetime"
+/>;
+```
+
+### Modes
+
+- `date` — Date only
+- `time` — Time only
+- `datetime` — Date and time
+
+### Display Styles
+
+```tsx
+// Compact inline (default)
+<DateTimePicker value={date} mode="date" />
+
+// Spinner wheel
+<DateTimePicker
+  value={date}
+  mode="date"
+  display="spinner"
+  style={{ width: 200, height: 150 }}
+/>
+
+// Full calendar
+<DateTimePicker value={date} mode="date" display="inline" />
+```
+
+### Time Intervals
+
+```tsx
+<DateTimePicker
+  value={date}
+  mode="time"
+  minuteInterval={15}
+/>
+```
+
+### Min/Max Dates
+
+```tsx
+<DateTimePicker
+  value={date}
+  mode="date"
+  minimumDate={new Date(2020, 0, 1)}
+  maximumDate={new Date(2030, 11, 31)}
+/>
+```
+
+## Stepper
+
+Increment/decrement numeric values.
+
+```tsx
+import { Stepper } from "react-native";
+import { useState } from "react";
+
+const [count, setCount] = useState(0);
+
+<Stepper
+  value={count}
+  onValueChange={setCount}
+  minimumValue={0}
+  maximumValue={10}
+/>;
+```
+
+## TextInput
+
+Native text input with various keyboard types.
+
+```tsx
+import { TextInput } from "react-native";
+
+<TextInput
+  placeholder="Enter text..."
+  placeholderTextColor="#999"
+  style={{
+    padding: 12,
+    fontSize: 16,
+    borderRadius: 8,
+    backgroundColor: "#f0f0f0",
+  }}
+/>
+```
+
+### Keyboard Types
+
+```tsx
+// Email
+<TextInput keyboardType="email-address" autoCapitalize="none" />
+
+// Phone
+<TextInput keyboardType="phone-pad" />
+
+// Number
+<TextInput keyboardType="numeric" />
+
+// Password
+<TextInput secureTextEntry />
+
+// Search
+<TextInput
+  returnKeyType="search"
+  enablesReturnKeyAutomatically
+/>
+```
+
+### Multiline
+
+```tsx
+<TextInput
+  multiline
+  numberOfLines={4}
+  textAlignVertical="top"
+  style={{ minHeight: 100 }}
+/>
+```
+
+## Picker (Wheel)
+
+For selection from many options (5+ items).
+
+```tsx
+import { Picker } from "@react-native-picker/picker";
+import { useState } from "react";
+
+const [selected, setSelected] = useState("js");
+
+<Picker selectedValue={selected} onValueChange={setSelected}>
+  <Picker.Item label="JavaScript" value="js" />
+  <Picker.Item label="TypeScript" value="ts" />
+  <Picker.Item label="Python" value="py" />
+  <Picker.Item label="Go" value="go" />
+</Picker>;
+```
+
+## Best Practices
+
+- **Haptics**: Switch and DateTimePicker have built-in haptics — don't add extra
+- **Accessibility**: Native controls have proper accessibility labels by default
+- **Dark Mode**: Avoid custom colors — native styling adapts automatically
+- **Spacing**: Use consistent padding around controls (12-16pt)
+- **Labels**: Place labels above or to the left of controls
+- **Grouping**: Group related controls in sections with headers

+# Form Sheets in Expo Router
+
+This skill covers implementing form sheets with footers using Expo Router's Stack navigator and react-native-screens.
+
+## Overview
+
+Form sheets are modal presentations that appear as a card sliding up from the bottom of the screen. They're ideal for:
+
+- Quick actions and confirmations
+- Settings panels
+- Login/signup flows
+- Action sheets with custom content
+
+**Requirements:**
+
+- Expo Router Stack navigator
+
+## Basic Usage
+
+### Form Sheet with Footer
+
+Configure the Stack.Screen with transparent backgrounds and sheet presentation:
+
+```tsx
+// app/_layout.tsx
+import { Stack } from "expo-router";
+
+export default function Layout() {
+  return (
+    <Stack>
+      <Stack.Screen name="index" />
+      <Stack.Screen
+        name="about"
+        options={{
+          presentation: "formSheet",
+          sheetAllowedDetents: [0.25],
+          headerTransparent: true,
+          contentStyle: { backgroundColor: "transparent" },
+          sheetGrabberVisible: true,
+        }}
+      >
+        <Stack.Header style={{ backgroundColor: "transparent" }}></Stack.Header>
+      </Stack.Screen>
+    </Stack>
+  );
+}
+```
+
+### Form Sheet Screen Content
+
+> Requires Expo SDK 55 or later.
+
+Use `flex: 1` to allow the content to fill available space, enabling footer positioning:
+
+```tsx
+// app/about.tsx
+import { View, Text, StyleSheet } from "react-native";
+
+export default function AboutSheet() {
+  return (
+    <View style={styles.container}>
+      {/* Main content */}
+      <View style={styles.content}>
+        <Text>Sheet Content</Text>
+      </View>
+
+      {/* Footer - stays at bottom */}
+      <View style={styles.footer}>
+        <Text>Footer Content</Text>
+      </View>
+    </View>
+  );
+}
+
+const styles = StyleSheet.create({
+  container: {
+    flex: 1,
+  },
+  content: {
+    flex: 1,
+    padding: 16,
+  },
+  footer: {
+    padding: 16,
+  },
+});
+```
+
+### Formsheet with interactive content below
+
+Use `sheetLargestUndimmedDetentIndex` (zero-indexed) to keep content behind the form sheet interactive — e.g. letting users pan a map beneath it. Setting it to `1` allows interaction at the first two detents but dims on the third.
+
+```tsx
+// app/_layout.tsx
+import { Stack } from 'expo-router';
+
+export default function Layout() {
+  return (
+    <Stack screenOptions={{ headerShown: false }}>
+      <Stack.Screen name="index" />
+      <Stack.Screen
+        name="info-sheet"
+        options={{
+          presentation: "formSheet",
+          sheetAllowedDetents: [0.2, 0.5, 1.0],
+          sheetLargestUndimmedDetentIndex: 1,
+          /* other options */
+        }}
+      />
+    </Stack>
+  )
+}
+```
+
+## Key Options
+
+| Option                | Type       | Description                                                 |
+| --------------------- | ---------- | ----------------------------------------------------------- |
+| `presentation`        | `string`   | Set to `'formSheet'` for sheet presentation                 |
+| `sheetGrabberVisible` | `boolean`  | Shows the drag handle at the top of the sheet               |
+| `sheetAllowedDetents` | `number[]` | Array of detent heights (0-1 range, e.g., `[0.25]` for 25%) |
+| `headerTransparent`   | `boolean`  | Makes header background transparent                         |
+| `contentStyle`        | `object`   | Style object for the screen content container               |
+| `title`               | `string`   | Screen title (set to `''` for no title)                     |
+
+## Common Detent Values
+
+- `[0.25]` - Quarter sheet (compact actions)
+- `[0.5]` - Half sheet (medium content)
+- `[0.75]` - Three-quarter sheet (detailed forms)
+- `[0.25, 0.5, 1]` - Multiple stops (expandable sheet)
+
+## Complete Example
+
+```tsx
+// _layout.tsx
+import { Stack } from "expo-router";
+
+export default function Layout() {
+  return (
+    <Stack>
+      <Stack.Screen name="index" options={{ title: "Home" }} />
+      <Stack.Screen
+        name="confirm"
+        options={{
+          contentStyle: { backgroundColor: "transparent" },
+          presentation: "formSheet",
+          title: "",
+          sheetGrabberVisible: true,
+          sheetAllowedDetents: [0.25],
+          headerTransparent: true,
+        }}
+      >
+        <Stack.Header style={{ backgroundColor: "transparent" }}>
+          <Stack.Header.Right />
+        </Stack.Header>
+      </Stack.Screen>
+    </Stack>
+  );
+}
+```
+
+```tsx
+// app/confirm.tsx
+import { View, Text, Pressable, StyleSheet } from "react-native";
+import { router } from "expo-router";
+
+export default function ConfirmSheet() {
+  return (
+    <View style={styles.container}>
+      <View style={styles.content}>
+        <Text style={styles.title}>Confirm Action</Text>
+        <Text style={styles.description}>
+          Are you sure you want to proceed?
+        </Text>
+      </View>
+
+      <View style={styles.footer}>
+        <Pressable style={styles.cancelButton} onPress={() => router.back()}>
+          <Text style={styles.cancelText}>Cancel</Text>
+        </Pressable>
+        <Pressable style={styles.confirmButton} onPress={() => router.back()}>
+          <Text style={styles.confirmText}>Confirm</Text>
+        </Pressable>
+      </View>
+    </View>
+  );
+}
+
+const styles = StyleSheet.create({
+  container: {
+    flex: 1,
+  },
+  content: {
+    flex: 1,
+    padding: 20,
+    alignItems: "center",
+    justifyContent: "center",
+  },
+  title: {
+    fontSize: 18,
+    fontWeight: "600",
+    marginBottom: 8,
+  },
+  description: {
+    fontSize: 14,
+    color: "#666",
+    textAlign: "center",
+  },
+  footer: {
+    flexDirection: "row",
+    padding: 16,
+    gap: 12,
+  },
+  cancelButton: {
+    flex: 1,
+    padding: 14,
+    borderRadius: 10,
+    backgroundColor: "#f0f0f0",
+    alignItems: "center",
+  },
+  cancelText: {
+    fontSize: 16,
+    fontWeight: "500",
+  },
+  confirmButton: {
+    flex: 1,
+    padding: 14,
+    borderRadius: 10,
+    backgroundColor: "#007AFF",
+    alignItems: "center",
+  },
+  confirmText: {
+    fontSize: 16,
+    fontWeight: "500",
+    color: "white",
+  },
+});
+```
+
+## Troubleshooting
+
+### Content not filling sheet
+
+Make sure the root View uses `flex: 1`:
+
+```tsx
+<View style={{ flex: 1 }}>{/* content */}</View>
+```
+
+### Sheet background showing through
+
+Set `contentStyle: { backgroundColor: 'transparent' }` in options and style your content container with the desired background color instead.

+# CSS Gradients
+
+> **New Architecture Only**: CSS gradients require React Native's New Architecture (Fabric). They are not available in the old architecture or Expo Go.
+
+Use CSS gradients with the `experimental_backgroundImage` style property.
+
+## Linear Gradients
+
+```tsx
+// Top to bottom
+<View style={{
+  experimental_backgroundImage: 'linear-gradient(to bottom, rgba(0, 0, 0, 0) 0%, rgba(0, 0, 0, 1) 100%)'
+}} />
+
+// Left to right
+<View style={{
+  experimental_backgroundImage: 'linear-gradient(to right, #ff0000 0%, #0000ff 100%)'
+}} />
+
+// Diagonal
+<View style={{
+  experimental_backgroundImage: 'linear-gradient(45deg, #ff0000 0%, #00ff00 50%, #0000ff 100%)'
+}} />
+
+// Using degrees
+<View style={{
+  experimental_backgroundImage: 'linear-gradient(135deg, transparent 0%, black 100%)'
+}} />
+```
+
+## Radial Gradients
+
+```tsx
+// Circle at center
+<View style={{
+  experimental_backgroundImage: 'radial-gradient(circle at center, rgba(255, 0, 0, 1) 0%, rgba(0, 0, 255, 1) 100%)'
+}} />
+
+// Ellipse
+<View style={{
+  experimental_backgroundImage: 'radial-gradient(ellipse at center, #fff 0%, #000 100%)'
+}} />
+
+// Positioned
+<View style={{
+  experimental_backgroundImage: 'radial-gradient(circle at top left, #ff0000 0%, transparent 70%)'
+}} />
+```
+
+## Multiple Gradients
+
+Stack multiple gradients by comma-separating them:
+
+```tsx
+<View style={{
+  experimental_backgroundImage: `
+    linear-gradient(to bottom, transparent 0%, black 100%),
+    radial-gradient(circle at top right, rgba(255, 0, 0, 0.5) 0%, transparent 50%)
+  `
+}} />
+```
+
+## Common Patterns
+
+### Overlay on Image
+
+```tsx
+<View style={{ position: 'relative' }}>
+  <Image source={{ uri: '...' }} style={{ width: '100%', height: 200 }} />
+  <View style={{
+    position: 'absolute',
+    inset: 0,
+    experimental_backgroundImage: 'linear-gradient(to top, rgba(0, 0, 0, 0.8) 0%, transparent 50%)'
+  }} />
+</View>
+```
+
+### Frosted Glass Effect
+
+```tsx
+<View style={{
+  experimental_backgroundImage: 'linear-gradient(135deg, rgba(255, 255, 255, 0.1) 0%, rgba(255, 255, 255, 0.05) 100%)',
+  backdropFilter: 'blur(10px)',
+}} />
+```
+
+### Button Gradient
+
+```tsx
+<Pressable style={{
+  experimental_backgroundImage: 'linear-gradient(to bottom, #4CAF50 0%, #388E3C 100%)',
+  padding: 16,
+  borderRadius: 8,
+}}>
+  <Text style={{ color: 'white', textAlign: 'center' }}>Submit</Text>
+</Pressable>
+```
+
+## Important Notes
+
+- Do NOT use `expo-linear-gradient` — use CSS gradients instead
+- Gradients are strings, not objects
+- Use `rgba()` for transparency, or `transparent` keyword
+- Color stops use percentages (0%, 50%, 100%)
+- Direction keywords: `to top`, `to bottom`, `to left`, `to right`, `to top left`, etc.
+- Degree values: `45deg`, `90deg`, `135deg`, etc.

+# Icons (SF Symbols)
+
+Use SF Symbols for native feel. Never use FontAwesome or Ionicons.
+
+## Basic Usage
+
+```tsx
+import { SymbolView } from "expo-symbols";
+import { PlatformColor } from "react-native";
+
+<SymbolView
+  tintColor={PlatformColor("label")}
+  resizeMode="scaleAspectFit"
+  name="square.and.arrow.down"
+  style={{ width: 16, height: 16 }}
+/>;
+```
+
+## Props
+
+```tsx
+<SymbolView
+  name="star.fill"                    // SF Symbol name (required)
+  tintColor={PlatformColor("label")}  // Icon color
+  size={24}                           // Shorthand for width/height
+  resizeMode="scaleAspectFit"         // How to scale
+  weight="regular"                    // thin | ultraLight | light | regular | medium | semibold | bold | heavy | black
+  scale="medium"                      // small | medium | large

+animationSpec={{
+  effect: { type: "pulse" }
+}}
+
+// Variable color (multicolor symbols)
+animationSpec={{
+  effect: {
+    type: "variableColor",
+    cumulative: true,
+    reversing: true
+  }
+}}
+```
+
+## Symbol Weights
+
+```tsx
+// Lighter weights
+<SymbolView name="star" weight="ultraLight" />
+<SymbolView name="star" weight="thin" />
+<SymbolView name="star" weight="light" />
+
+// Default
+<SymbolView name="star" weight="regular" />
+
+// Heavier weights
+<SymbolView name="star" weight="medium" />
+<SymbolView name="star" weight="semibold" />
+<SymbolView name="star" weight="bold" />
+<SymbolView name="star" weight="heavy" />
+<SymbolView name="star" weight="black" />
+```
+
+## Symbol Scales
+
+```tsx
+<SymbolView name="star" scale="small" />
+<SymbolView name="star" scale="medium" />  // default
+<SymbolView name="star" scale="large" />
+```
+
+## Multicolor Symbols
+
+Some symbols support multiple colors:
+
+```tsx
+<SymbolView
+  name="cloud.sun.rain.fill"
+  type="multicolor"
+/>
+```
+
+## Finding Symbol Names
+
+1. Use the SF Symbols app on macOS (free from Apple)
+2. Search at https://developer.apple.com/sf-symbols/
+3. Symbol names use dot notation: `square.and.arrow.up`
+
+## Best Practices
+
+- Always use SF Symbols over vector icon libraries
+- Match symbol weight to nearby text weight
+- Use `.fill` variants for selected/active states
+- Use PlatformColor for tint to support dark mode
+- Keep icons at consistent sizes (16, 20, 24, 32)

+# Media
+
+## Camera
+
+- Hide navigation headers when there's a full screen camera
+- Ensure to flip the camera with `mirror` to emulate social apps
+- Use liquid glass buttons on cameras
+- Icons: `arrow.triangle.2.circlepath` (flip), `photo` (gallery), `bolt` (flash)
+- Eagerly request camera permission
+- Lazily request media library permission
+
+```tsx
+import React, { useRef, useState } from "react";

+        </View>
+      </View>
+    </View>
+  );
+}
+```
+
+## Audio Playback
+
+Use `expo-audio` not `expo-av`:
+
+```tsx
+import { useAudioPlayer } from 'expo-audio';
+
+const player = useAudioPlayer({ uri: 'https://stream.nightride.fm/rektory.mp3' });
+
+<Button title="Play" onPress={() => player.play()} />
+```
+
+## Audio Recording (Microphone)
+
+```tsx
+import {
+  useAudioRecorder,
+  AudioModule,
+  RecordingPresets,
+  setAudioModeAsync,
+  useAudioRecorderState,
+} from 'expo-audio';
+import { useEffect } from 'react';
+import { Alert, Button } from 'react-native';
+
+function App() {
+  const audioRecorder = useAudioRecorder(RecordingPresets.HIGH_QUALITY);
+  const recorderState = useAudioRecorderState(audioRecorder);
+
+  const record = async () => {
+    await audioRecorder.prepareToRecordAsync();
+    audioRecorder.record();
+  };
+
+  const stop = () => audioRecorder.stop();
+
+  useEffect(() => {
+    (async () => {
+      const status = await AudioModule.requestRecordingPermissionsAsync();
+      if (status.granted) {
+        setAudioModeAsync({ playsInSilentMode: true, allowsRecording: true });
+      } else {
+        Alert.alert('Permission to access microphone was denied');
+      }
+    })();
+  }, []);
+
+  return (
+    <Button
+      title={recorderState.isRecording ? 'Stop' : 'Start'}
+      onPress={recorderState.isRecording ? stop : record}
+    />
+  );
+}
+```
+
+## Video Playback
+
+Use `expo-video` not `expo-av`:
+
+```tsx
+import { useVideoPlayer, VideoView } from 'expo-video';
+import { useEvent } from 'expo';
+
+const videoSource = 'https://example.com/video.mp4';
+
+const player = useVideoPlayer(videoSource, player => {
+  player.loop = true;
+  player.play();
+});
+
+const { isPlaying } = useEvent(player, 'playingChange', { isPlaying: player.playing });
+
+<VideoView player={player} fullscreenOptions={{}} allowsPictureInPicture />
+```
+
+VideoView options:
+- `allowsPictureInPicture`: boolean
+- `contentFit`: 'contain' | 'cover' | 'fill'
+- `nativeControls`: boolean
+- `playsInline`: boolean
+- `startsPictureInPictureAutomatically`: boolean
+
+## Saving Media
+
+```tsx
+import * as MediaLibrary from "expo-media-library";
+
+const { granted } = await MediaLibrary.requestPermissionsAsync();
+if (granted) {
+  await MediaLibrary.saveToLibraryAsync(uri);
+}
+```
+
+### Saving Base64 Images
+
+`MediaLibrary.saveToLibraryAsync` only accepts local file paths. Save base64 strings to disk first:
+
+```tsx
+import { File, Paths } from "expo-file-system/next";
+
+function base64ToLocalUri(base64: string, filename?: string) {
+  if (!filename) {
+    const match = base64.match(/^data:(image\/[a-zA-Z]+);base64,/);
+    const ext = match ? match[1].split("/")[1] : "jpg";
+    filename = `generated-${Date.now()}.${ext}`;
+  }
+
+  if (base64.startsWith("data:")) base64 = base64.split(",")[1];
+  const binaryString = atob(base64);
+  const len = binaryString.length;
+  const bytes = new Uint8Array(new ArrayBuffer(len));
+  for (let i = 0; i < len; i++) bytes[i] = binaryString.charCodeAt(i);
+
+  const f = new File(Paths.cache, filename);
+  f.create({ overwrite: true });
+  f.write(bytes);
+  return f.uri;
+}
+```

+# Route Structure
+
+## File Conventions
+
+- Routes belong in the `app` directory
+- Use `[]` for dynamic routes, e.g. `[id].tsx`
+- Routes can never be named `(foo).tsx` - use `(foo)/index.tsx` instead
+- Use `(group)` routes to simplify the public URL structure
+- NEVER co-locate components, types, or utilities in the app directory - these should be in separate directories like `components/`, `utils/`, etc.
+- The app directory should only contain route and `_layout` files; every file should export a default component
+- Ensure the app always has a route that matches "/" so the app is never blank
+- ALWAYS use `_layout.tsx` files to define stacks
+
+## Dynamic Routes
+
+Use square brackets for dynamic segments:
+
+```
+app/
+  users/
+    [id].tsx        # Matches /users/123, /users/abc
+    [id]/
+      posts.tsx     # Matches /users/123/posts
+```
+
+### Catch-All Routes
+
+Use `[...slug]` for catch-all routes:
+
+```
+app/
+  docs/
+    [...slug].tsx   # Matches /docs/a, /docs/a/b, /docs/a/b/c
+```
+
+## Query Parameters
+
+Access query parameters with the `useLocalSearchParams` hook:
+
+```tsx
+import { useLocalSearchParams } from "expo-router";
+
+function Page() {
+  const { id } = useLocalSearchParams<{ id: string }>();
+}
+```
+
+For dynamic routes, the parameter name matches the file name:
+
+- `[id].tsx` → `useLocalSearchParams<{ id: string }>()`
+- `[slug].tsx` → `useLocalSearchParams<{ slug: string }>()`
+
+## Pathname
+
+Access the current pathname with the `usePathname` hook:
+
+```tsx
+import { usePathname } from "expo-router";
+
+function Component() {
+  const pathname = usePathname(); // e.g. "/users/123"
+}
+```
+
+## Group Routes
+
+Use parentheses for groups that don't affect the URL:
+
+```
+app/
+  (auth)/
+    login.tsx       # URL: /login
+    register.tsx    # URL: /register
+  (main)/
+    index.tsx       # URL: /
+    settings.tsx    # URL: /settings
+```
+
+Groups are useful for:
+
+- Organizing related routes
+- Applying different layouts to route groups
+- Keeping URLs clean
+
+## Stacks and Tabs Structure
+
+When an app has tabs, the header and title should be set in a Stack that is nested INSIDE each tab. This allows tabs to have their own headers and distinct histories. The root layout should often not have a header.
+
+- Set the 'headerShown' option to false on the tab layout
+- Use (group) routes to simplify the public URL structure
+- You may need to delete or refactor existing routes to fit this structure
+
+Example structure:
+
+```
+app/
+  _layout.tsx — <Tabs />
+  (home)/
+    _layout.tsx — <Stack />
+    index.tsx — <ScrollView />
+  (settings)/
+    _layout.tsx — <Stack />
+    index.tsx — <ScrollView />
+  (home,settings)/
+    info.tsx — <ScrollView /> (shared across tabs)
+```
+
+## Array Routes for Multiple Stacks
+
+Use array routes '(index,settings)' to create multiple stacks. This is useful for tabs that need to share screens across stacks.
+
+```
+app/
+  _layout.tsx — <Tabs />
+  (index,settings)/
+    _layout.tsx — <Stack />
+    index.tsx — <ScrollView />
+    settings.tsx — <ScrollView />
+```
+
+This requires a specialized layout with explicit anchor routes:
+
+```tsx
+// app/(index,settings)/_layout.tsx
+import { useMemo } from "react";
+import Stack from "expo-router/stack";
+
+export const unstable_settings = {
+  index: { anchor: "index" },
+  settings: { anchor: "settings" },
+};
+
+export default function Layout({ segment }: { segment: string }) {
+  const screen = segment.match(/\((.*)\)/)?.[1]!;
+
+  const options = useMemo(() => {
+    switch (screen) {
+      case "index":
+        return { headerRight: () => <></> };
+      default:
+        return {};
+    }
+  }, [screen]);
+
+  return (
+    <Stack>
+      <Stack.Screen name={screen} options={options} />
+    </Stack>
+  );
+}
+```
+
+## Complete App Structure Example
+
+```
+app/
+  _layout.tsx — <NativeTabs />
+  (index,search)/
+    _layout.tsx — <Stack />
+    index.tsx — Main list
+    search.tsx — Search view
+    i/[id].tsx — Detail page
+components/
+  theme.tsx
+  list.tsx
+utils/
+  storage.ts
+  use-search.ts
+```
+
+## Layout Files
+
+Every directory can have a `_layout.tsx` file that wraps all routes in that directory:
+
+```tsx
+// app/_layout.tsx
+import { Stack } from "expo-router/stack";
+
+export default function RootLayout() {
+  return <Stack />;
+}
+```
+
+```tsx
+// app/(tabs)/_layout.tsx
+import { NativeTabs, Icon, Label } from "expo-router/unstable-native-tabs";
+
+export default function TabLayout() {
+  return (
+    <NativeTabs>
+      <NativeTabs.Trigger name="index">
+        <Label>Home</Label>
+        <Icon sf="house.fill" />
+      </NativeTabs.Trigger>
+    </NativeTabs>
+  );
+}
+```
+
+## Route Settings
+
+Export `unstable_settings` to configure route behavior:
+
+```tsx
+export const unstable_settings = {
+  anchor: "index",
+};
+```
+
+- `initialRouteName` was renamed to `anchor` in v4
+
+## Not Found Routes
+
+Create a `+not-found.tsx` file to handle unmatched routes:
+
+```tsx
+// app/+not-found.tsx
+import { Link } from "expo-router";
+import { View, Text } from "react-native";
+
+export default function NotFound() {
+  return (
+    <View>
+      <Text>Page not found</Text>
+      <Link href="/">Go home</Link>
+    </View>
+  );
+}
+```

+# Search
+
+## Header Search Bar
+
+Add a search bar to the stack header with `headerSearchBarOptions`:
+
+```tsx
+<Stack.Screen
+  name="index"
+  options={{
+    headerSearchBarOptions: {
+      placeholder: "Search",
+      onChangeText: (event) => console.log(event.nativeEvent.text),
+    },
+  }}
+/>
+```
+
+### Options
+
+```tsx
+headerSearchBarOptions: {
+  // Placeholder text
+  placeholder: "Search items...",
+
+  // Auto-capitalize behavior
+  autoCapitalize: "none",
+
+  // Input type
+  inputType: "text", // "text" | "phone" | "number" | "email"
+
+  // Cancel button text (iOS)
+  cancelButtonText: "Cancel",
+
+  // Hide when scrolling (iOS)
+  hideWhenScrolling: true,
+
+  // Hide navigation bar during search (iOS)
+  hideNavigationBar: true,
+
+  // Obscure background during search (iOS)
+  obscureBackground: true,
+
+  // Placement
+  placement: "automatic", // "automatic" | "inline" | "stacked"
+
+  // Callbacks
+  onChangeText: (event) => {},
+  onSearchButtonPress: (event) => {},
+  onCancelButtonPress: (event) => {},
+  onFocus: () => {},
+  onBlur: () => {},
+}
+```
+
+## useSearch Hook
+
+Reusable hook for search state management:
+
+```tsx
+import { useEffect, useState } from "react";
+import { useNavigation } from "expo-router";
+
+export function useSearch(options: any = {}) {
+  const [search, setSearch] = useState("");
+  const navigation = useNavigation();
+
+  useEffect(() => {
+    navigation.setOptions({
+      headerShown: true,
+      headerSearchBarOptions: {
+        ...options,
+        onChangeText(e: any) {
+          setSearch(e.nativeEvent.text);
+          options.onChangeText?.(e);
+        },
+        onSearchButtonPress(e: any) {
+          setSearch(e.nativeEvent.text);
+          options.onSearchButtonPress?.(e);
+        },
+        onCancelButtonPress(e: any) {
+          setSearch("");
+          options.onCancelButtonPress?.(e);
+        },
+      },
+    });
+  }, [options, navigation]);
+
+  return search;
+}
+```
+
+### Usage
+
+```tsx
+function SearchScreen() {
+  const search = useSearch({ placeholder: "Search items..." });
+
+  const filteredItems = items.filter(item =>
+    item.name.toLowerCase().includes(search.toLowerCase())
+  );
+
+  return (
+    <FlatList
+      data={filteredItems}
+      renderItem={({ item }) => <ItemRow item={item} />}
+    />
+  );
+}
+```
+
+## Filtering Patterns
+
+### Simple Text Filter
+
+```tsx
+const filtered = items.filter(item =>
+  item.name.toLowerCase().includes(search.toLowerCase())
+);
+```
+
+### Multiple Fields
+
+```tsx
+const filtered = items.filter(item => {
+  const query = search.toLowerCase();
+  return (
+    item.name.toLowerCase().includes(query) ||
+    item.description.toLowerCase().includes(query) ||
+    item.tags.some(tag => tag.toLowerCase().includes(query))
+  );
+});
+```
+
+### Debounced Search
+
+For expensive filtering or API calls:
+
+```tsx
+import { useState, useEffect, useMemo } from "react";
+
+function useDebounce<T>(value: T, delay: number): T {
+  const [debounced, setDebounced] = useState(value);
+
+  useEffect(() => {
+    const timer = setTimeout(() => setDebounced(value), delay);
+    return () => clearTimeout(timer);
+  }, [value, delay]);
+
+  return debounced;
+}
+
+function SearchScreen() {
+  const search = useSearch();
+  const debouncedSearch = useDebounce(search, 300);
+
+  const filteredItems = useMemo(() =>
+    items.filter(item =>
+      item.name.toLowerCase().includes(debouncedSearch.toLowerCase())
+    ),
+    [debouncedSearch]
+  );
+
+  return <FlatList data={filteredItems} />;
+}
+```
+
+## Search with Native Tabs
+
+When using NativeTabs with a search role, the search bar integrates with the tab bar:
+
+```tsx
+// app/_layout.tsx
+<NativeTabs>
+  <NativeTabs.Trigger name="(home)">
+    <Label>Home</Label>
+    <Icon sf="house.fill" />
+  </NativeTabs.Trigger>
+  <NativeTabs.Trigger name="(search)" role="search">
+    <Label>Search</Label>
+  </NativeTabs.Trigger>
+</NativeTabs>
+```
+
+```tsx
+// app/(search)/_layout.tsx
+<Stack>
+  <Stack.Screen
+    name="index"
+    options={{
+      headerSearchBarOptions: {
+        placeholder: "Search...",
+        onChangeText: (e) => setSearch(e.nativeEvent.text),
+      },
+    }}
+  />
+</Stack>
+```
+
+## Empty States
+
+Show appropriate UI when search returns no results:
+
+```tsx
+function SearchResults({ search, items }) {
+  const filtered = items.filter(/* ... */);
+
+  if (search && filtered.length === 0) {
+    return (
+      <View style={{ flex: 1, justifyContent: "center", alignItems: "center" }}>
+        <Text style={{ color: PlatformColor("secondaryLabel") }}>
+          No results for "{search}"
+        </Text>
+      </View>
+    );
+  }
+
+  return <FlatList data={filtered} />;
+}
+```
+
+## Search Suggestions
+
+Show recent searches or suggestions:
+
+```tsx
+function SearchScreen() {
+  const search = useSearch();
+  const [recentSearches, setRecentSearches] = useState<string[]>([]);
+
+  if (!search && recentSearches.length > 0) {
+    return (
+      <View>
+        <Text style={{ color: PlatformColor("secondaryLabel") }}>
+          Recent Searches
+        </Text>
+        {recentSearches.map((term) => (
+          <Pressable key={term} onPress={() => /* apply search */}>
+            <Text>{term}</Text>
+          </Pressable>
+        ))}
+      </View>
+    );
+  }
+
+  return <SearchResults search={search} />;
+}

+# Storage
+
+## Key-Value Storage
+
+Use the localStorage polyfill for key-value storage. **Never use AsyncStorage**
+
+```tsx
+import "expo-sqlite/localStorage/install";
+
+// Simple get/set
+localStorage.setItem("key", "value");
+localStorage.getItem("key");
+
+// Store objects as JSON
+localStorage.setItem("user", JSON.stringify({ name: "John", id: 1 }));
+const user = JSON.parse(localStorage.getItem("user") ?? "{}");
+```
+
+## When to Use What
+
+| Use Case                                             | Solution                |
+| ---------------------------------------------------- | ----------------------- |
+| Simple key-value (settings, preferences, small data) | `localStorage` polyfill |
+| Large datasets, complex queries, relational data     | Full `expo-sqlite`      |
+| Sensitive data (tokens, passwords)                   | `expo-secure-store`     |
+
+## Storage with React State
+
+Create a storage utility with subscriptions for reactive updates:
+
+```tsx
+// utils/storage.ts
+import "expo-sqlite/localStorage/install";
+
+type Listener = () => void;
+const listeners = new Map<string, Set<Listener>>();
+
+export const storage = {
+  get<T>(key: string, defaultValue: T): T {
+    const value = localStorage.getItem(key);
+    return value ? JSON.parse(value) : defaultValue;
+  },
+
+  set<T>(key: string, value: T): void {
+    localStorage.setItem(key, JSON.stringify(value));
+    listeners.get(key)?.forEach((fn) => fn());
+  },
+
+  subscribe(key: string, listener: Listener): () => void {
+    if (!listeners.has(key)) listeners.set(key, new Set());
+    listeners.get(key)!.add(listener);
+    return () => listeners.get(key)?.delete(listener);
+  },
+};
+```
+
+## React Hook for Storage
+
+```tsx
+// hooks/use-storage.ts
+import { useSyncExternalStore } from "react";
+import { storage } from "@/utils/storage";
+
+export function useStorage<T>(
+  key: string,
+  defaultValue: T
+): [T, (value: T) => void] {
+  const value = useSyncExternalStore(
+    (cb) => storage.subscribe(key, cb),
+    () => storage.get(key, defaultValue)
+  );
+
+  return [value, (newValue: T) => storage.set(key, newValue)];
+}
+```
+
+Usage:
+
+```tsx
+function Settings() {
+  const [theme, setTheme] = useStorage("theme", "light");
+
+  return (
+    <Switch
+      value={theme === "dark"}
+      onValueChange={(dark) => setTheme(dark ? "dark" : "light")}
+    />
+  );
+}
+```
+
+## Full SQLite for Complex Data
+
+For larger datasets or complex queries, use expo-sqlite directly:
+
+```tsx
+import * as SQLite from "expo-sqlite";
+
+const db = await SQLite.openDatabaseAsync("app.db");
+
+// Create table
+await db.execAsync(`
+  CREATE TABLE IF NOT EXISTS events (
+    id INTEGER PRIMARY KEY AUTOINCREMENT,
+    title TEXT NOT NULL,
+    date TEXT NOT NULL,
+    location TEXT
+  )
+`);
+
+// Insert
+await db.runAsync("INSERT INTO events (title, date) VALUES (?, ?)", [
+  "Meeting",
+  "2024-01-15",
+]);
+
+// Query
+const events = await db.getAllAsync("SELECT * FROM events WHERE date > ?", [
+  "2024-01-01",
+]);

+# Native Tabs
+
+Always prefer NativeTabs from 'expo-router/unstable-native-tabs' for the best iOS experience.
+
+**SDK 54+. SDK 55 recommended.**
+
+## SDK Compatibility
+
+| Aspect        | SDK 54                                                  | SDK 55+                                                     |
+| ------------- | ------------------------------------------------------- | ----------------------------------------------------------- |
+| Import        | `import { NativeTabs, Icon, Label, Badge, VectorIcon }` | `import { NativeTabs }` only                                |
+| Icon          | `<Icon sf="house.fill" />`                              | `<NativeTabs.Trigger.Icon sf="house.fill" />`               |
+| Label         | `<Label>Home</Label>`                                   | `<NativeTabs.Trigger.Label>Home</NativeTabs.Trigger.Label>` |
+| Badge         | `<Badge>9+</Badge>`                                     | `<NativeTabs.Trigger.Badge>9+</NativeTabs.Trigger.Badge>`   |
+| Android icons | `drawable` prop                                         | `md` prop (Material Symbols)                                |
+
+All examples below use SDK 55 syntax. For SDK 54, replace `NativeTabs.Trigger.Icon/Label/Badge` with standalone `Icon`, `Label`, `Badge` imports.
+
+## Basic Usage
+
+```tsx
+import { NativeTabs } from "expo-router/unstable-native-tabs";
+
+export default function TabLayout() {
+  return (
+    <NativeTabs minimizeBehavior="onScrollDown">
+      <NativeTabs.Trigger name="index">
+        <NativeTabs.Trigger.Icon sf="house.fill" md="home" />
+        <NativeTabs.Trigger.Label>Home</NativeTabs.Trigger.Label>
+        <NativeTabs.Trigger.Badge>9+</NativeTabs.Trigger.Badge>
+      </NativeTabs.Trigger>
+      <NativeTabs.Trigger name="settings">
+        <NativeTabs.Trigger.Icon sf="gear" md="settings" />
+        <NativeTabs.Trigger.Label>Settings</NativeTabs.Trigger.Label>
+      </NativeTabs.Trigger>
+      <NativeTabs.Trigger name="(search)" role="search">
+        <NativeTabs.Trigger.Label>Search</NativeTabs.Trigger.Label>
+      </NativeTabs.Trigger>
+    </NativeTabs>
+  );
+}
+```
+
+## Rules
+
+- You must include a trigger for each tab
+- The `NativeTabs.Trigger` 'name' must match the route name, including parentheses (e.g. `<NativeTabs.Trigger name="(search)">`)
+- Prefer search tab to be last in the list so it can combine with the search bar
+- Use the 'role' prop for common tab types
+- Tabs must be static — no dynamic addition/removal at runtime (remounts navigator, loses state)
+
+## Platform Features
+
+Native Tabs use platform-specific tab bar implementations:
+
+- **iOS 26+**: Liquid glass effects with system-native appearance
+- **Android**: Material 3 bottom navigation
+- Better performance and native feel
+
+## Icon Component
+
+```tsx
+// SF Symbol (iOS) + Material Symbol (Android)
+<NativeTabs.Trigger.Icon sf="house.fill" md="home" />
+
+// State variants
+<NativeTabs.Trigger.Icon sf={{ default: "house", selected: "house.fill" }} md="home" />
+
+// Custom image
+<NativeTabs.Trigger.Icon src={require('./icon.png')} />
+
+// Xcode asset catalog — iOS only (SDK 55+)
+<NativeTabs.Trigger.Icon xcasset="home-icon" />
+<NativeTabs.Trigger.Icon xcasset={{ default: "home-outline", selected: "home-filled" }} />
+
+// Rendering mode — iOS only (SDK 55+)
+<NativeTabs.Trigger.Icon src={require('./icon.png')} renderingMode="template" />
+<NativeTabs.Trigger.Icon src={require('./gradient.png')} renderingMode="original" />
+```
+
+`renderingMode`: `"template"` applies tint color (single-color icons), `"original"` preserves source colors (gradients). Android always uses original.
+
+## Label & Badge
+
+```tsx
+// Label
+<NativeTabs.Trigger.Label>Home</NativeTabs.Trigger.Label>
+<NativeTabs.Trigger.Label hidden>Home</NativeTabs.Trigger.Label>  {/* icon-only tab */}
+
+// Badge
+<NativeTabs.Trigger.Badge>9+</NativeTabs.Trigger.Badge>
+<NativeTabs.Trigger.Badge />  {/* dot indicator */}
+```
+
+## iOS 26 Features
+
+### Liquid Glass Tab Bar
+
+The tab bar automatically adopts liquid glass appearance on iOS 26+.
+
+### Minimize on Scroll
+
+```tsx
+<NativeTabs minimizeBehavior="onScrollDown">
+```
+
+### Search Tab
+
+```tsx
+<NativeTabs.Trigger name="(search)" role="search">
+  <NativeTabs.Trigger.Label>Search</NativeTabs.Trigger.Label>
+</NativeTabs.Trigger>
+```
+
+**Note**: Place search tab last for best UX.
+
+### Role Prop
+
+Use semantic roles for special tab types:
+
+```tsx
+<NativeTabs.Trigger name="search" role="search" />
+<NativeTabs.Trigger name="favorites" role="favorites" />
+<NativeTabs.Trigger name="more" role="more" />
+```
+
+Available roles: `search` | `more` | `favorites` | `bookmarks` | `contacts` | `downloads` | `featured` | `history` | `mostRecent` | `mostViewed` | `recents` | `topRated`
+
+## Customization
+
+### Tint Color
+
+```tsx
+<NativeTabs tintColor="#007AFF">
+```
+
+### Dynamic Colors (iOS)
+
+Use DynamicColorIOS for colors that adapt to liquid glass:
+
+```tsx
+import { DynamicColorIOS, Platform } from 'react-native';
+
+const adaptiveBlue = Platform.select({
+  ios: DynamicColorIOS({ light: '#007AFF', dark: '#0A84FF' }),
+  default: '#007AFF',
+});
+
+<NativeTabs tintColor={adaptiveBlue}>
+```
+
+## Conditional Tabs
+
+```tsx
+<NativeTabs.Trigger name="admin" hidden={!isAdmin}>
+  <NativeTabs.Trigger.Label>Admin</NativeTabs.Trigger.Label>
+  <NativeTabs.Trigger.Icon sf="shield.fill" md="shield" />
+</NativeTabs.Trigger>
+```
+
+**Don't hide the tabs when they are visible - toggling visibility remounts the navigator; Do it only during the initial render.**
+
+**Note**: Hidden tabs cannot be navigated to!
+
+## Behavior Options
+
+```tsx
+<NativeTabs.Trigger
+  name="home"
+  disablePopToTop           // Don't pop stack when tapping active tab
+  disableScrollToTop        // Don't scroll to top when tapping active tab
+  disableAutomaticContentInsets  // Opt out of automatic safe area insets (SDK 55+)
+>
+```
+
+## Hidden Tab Bar (SDK 55+)
+
+Use `hidden` prop on `NativeTabs` to hide the entire tab bar dynamically:
+
+```tsx
+<NativeTabs hidden={isTabBarHidden}>{/* triggers */}</NativeTabs>
+```
+
+## Bottom Accessory (SDK 55+)
+
+`NativeTabs.BottomAccessory` renders content above the tab bar (iOS 26+). Uses `usePlacement()` to adapt between `'regular'` and `'inline'` layouts.
+
+**Important**: Two instances render simultaneously — store state outside the component (props, context, or external store).
+
+```tsx
+import { NativeTabs } from "expo-router/unstable-native-tabs";
+import { useState } from "react";
+import { Pressable, Text, View } from "react-native";
+
+function MiniPlayer({
+  isPlaying,
+  onToggle,
+}: {
+  isPlaying: boolean;
+  onToggle: () => void;
+}) {
+  const placement = NativeTabs.BottomAccessory.usePlacement();
+  if (placement === "inline") {
+    return (
+      <Pressable onPress={onToggle}>
+        <SymbolView name={isPlaying ? "pause.fill" : "play.fill"} />
+      </Pressable>
+    );
+  }
+  return <View>{/* full player UI */}</View>;
+}
+
+export default function TabLayout() {
+  const [isPlaying, setIsPlaying] = useState(false);
+  return (
+    <NativeTabs>
+      <NativeTabs.BottomAccessory>
+        <MiniPlayer
+          isPlaying={isPlaying}
+          onToggle={() => setIsPlaying(!isPlaying)}
+        />
+      </NativeTabs.BottomAccessory>
+      <NativeTabs.Trigger name="index">
+        <NativeTabs.Trigger.Icon sf="house.fill" md="home" />
+        <NativeTabs.Trigger.Label>Home</NativeTabs.Trigger.Label>
+      </NativeTabs.Trigger>
+    </NativeTabs>
+  );
+}
+```
+
+## Safe Area Handling (SDK 55+)
+
+SDK 55 handles safe areas automatically:
+
+- **Android**: Content wrapped in SafeAreaView (bottom inset)
+- **iOS**: First ScrollView gets automatic `contentInsetAdjustmentBehavior`
+
+To opt out per-tab, use `disableAutomaticContentInsets` and manage manually:
+
+```tsx
+<NativeTabs.Trigger name="index" disableAutomaticContentInsets>
+  <NativeTabs.Trigger.Label>Home</NativeTabs.Trigger.Label>
+</NativeTabs.Trigger>
+```
+
+```tsx
+// In the screen
+import { SafeAreaView } from "react-native-screens/experimental";
+
+export default function HomeScreen() {
+  return (
+    <SafeAreaView edges={{ bottom: true }} style={{ flex: 1 }}>
+      {/* content */}
+    </SafeAreaView>
+  );
+}
+```
+
+## Using Vector Icons
+
+If you must use @expo/vector-icons instead of SF Symbols:
+
+```tsx
+import { NativeTabs } from "expo-router/unstable-native-tabs";
+import Ionicons from "@expo/vector-icons/Ionicons";
+
+<NativeTabs.Trigger name="home">
+  <NativeTabs.Trigger.VectorIcon vector={Ionicons} name="home" />
+  <NativeTabs.Trigger.Label>Home</NativeTabs.Trigger.Label>
+</NativeTabs.Trigger>
+```
+
+**Prefer SF Symbols + `md` prop over vector icons for native feel.**
+
+If you are using SDK 55 and later **use the md prop to specify Material Symbols used on Android**.
+
+## Structure with Stacks
+
+Native tabs don't render headers. Nest Stacks inside each tab for navigation headers:
+
+```tsx
+// app/(tabs)/_layout.tsx
+import { NativeTabs } from "expo-router/unstable-native-tabs";
+
+export default function TabLayout() {
+  return (
+    <NativeTabs>
+      <NativeTabs.Trigger name="(home)">
+        <NativeTabs.Trigger.Label>Home</NativeTabs.Trigger.Label>
+        <NativeTabs.Trigger.Icon sf="house.fill" md="home" />
+      </NativeTabs.Trigger>
+    </NativeTabs>
+  );
+}
+
+// app/(tabs)/(home)/_layout.tsx
+import Stack from "expo-router/stack";
+
+export default function HomeStack() {
+  return (
+    <Stack>
+      <Stack.Screen
+        name="index"
+        options={{ title: "Home", headerLargeTitle: true }}
+      />
+      <Stack.Screen name="details" options={{ title: "Details" }} />
+    </Stack>
+  );
+}
+```
+
+## Custom Web Layout
+
+Use platform-specific files for separate native and web tab layouts:
+
+```
+app/
+  _layout.tsx          # NativeTabs for iOS/Android
+  _layout.web.tsx      # Headless tabs for web (expo-router/ui)
+```
+
+Or extract to a component: `components/app-tabs.tsx` + `components/app-tabs.web.tsx`.
+
+## Migration from JS Tabs
+
+### Before (JS Tabs)
+
+```tsx
+import { Tabs } from "expo-router";
+
+<Tabs>
+  <Tabs.Screen
+    name="index"
+    options={{
+      title: "Home",
+      tabBarIcon: ({ color }) => <IconSymbol name="house.fill" color={color} />,
+      tabBarBadge: 3,
+    }}
+  />
+</Tabs>;
+```
+
+### After (Native Tabs)
+
+```tsx
+import { NativeTabs } from "expo-router/unstable-native-tabs";
+
+<NativeTabs>
+  <NativeTabs.Trigger name="index">
+    <NativeTabs.Trigger.Label>Home</NativeTabs.Trigger.Label>
+    <NativeTabs.Trigger.Icon sf="house.fill" md="home" />
+    <NativeTabs.Trigger.Badge>3</NativeTabs.Trigger.Badge>
+  </NativeTabs.Trigger>
+</NativeTabs>;
+```
+
+### Key Differences
+
+| JS Tabs                    | Native Tabs                  |
+| -------------------------- | ---------------------------- |
+| `<Tabs.Screen>`            | `<NativeTabs.Trigger>`       |
+| `options={{ title }}`      | `<NativeTabs.Trigger.Label>` |
+| `options={{ tabBarIcon }}` | `<NativeTabs.Trigger.Icon>`  |
+| `tabBarBadge` option       | `<NativeTabs.Trigger.Badge>` |
+| Props-based API            | Component-based API          |
+| Headers built-in           | Nest `<Stack>` for headers   |
+
+## Limitations
+
+- **Android**: Maximum 5 tabs (Material Design constraint)
+- **Nesting**: Native tabs cannot nest inside other native tabs
+- **Tab bar height**: Cannot be measured programmatically
+- **FlatList transparency**: Use `disableTransparentOnScrollEdge` to fix issues
+- **Dynamic tabs**: Tabs must be static; changes remount navigator and lose state
+
+## Keyboard Handling (Android)
+
+Configure in app.json:
+
+```json
+{
+  "expo": {
+    "android": {
+      "softwareKeyboardLayoutMode": "resize"
+    }
+  }
+}
+```
+
+## Common Issues
+
+1. **Icons not showing on Android**: Add `md` prop (SDK 55) or use VectorIcon
+2. **Headers missing**: Nest a Stack inside each tab group
+3. **Trigger name mismatch**: `name` must match exact route name including parentheses
+4. **Badge not visible**: Badge must be a child of Trigger, not a prop
+5. **Tab bar transparent on iOS 18 and earlier**: If the screen uses a `ScrollView` or `FlatList`, make sure it is the first opaque child of the screen component. If it needs to be wrapped in another `View`, ensure the wrapper uses `collapsable={false}`. If the screen does not use a `ScrollView` or `FlatList`, set `disableTransparentOnScrollEdge` to `true` in the `NativeTabs.Trigger` options, to make the tab bar opaque.
+6. **Scroll to top not working**: Ensure `disableScrollToTop` is not set on the active tab's Trigger and `ScrollView` is the first child of the screen component.
+7. **Header buttons flicker when navigating between tabs**: Make sure the app is wrapped in a `ThemeProvider`
+
+```tsx
+import {
+  ThemeProvider,
+  DarkTheme,
+  DefaultTheme,
+} from "@react-navigation/native";
+import { useColorScheme } from "react-native";
+import { Stack } from "expo-router";
+
+export default function Layout() {
+  const colorScheme = useColorScheme();
+  return (
+    <ThemeProvider theme={colorScheme === "dark" ? DarkTheme : DefaultTheme}>
+      <Stack />
+    </ThemeProvider>
+  );
+}
+```
+
+If the app only uses a light or dark theme, you can directly pass `DarkTheme` or `DefaultTheme` to `ThemeProvider` without checking the color scheme.
+
+```tsx
+import { ThemeProvider, DarkTheme } from "@react-navigation/native";
+import { Stack } from "expo-router";
+
+export default function Layout() {
+  return (
+    <ThemeProvider theme={DarkTheme}>
+      <Stack />
+    </ThemeProvider>
+  );
+}
+```

+    </>
+  );
+}
+```
+
+## Placement
+
+- `"left"` - Header left
+- `"right"` - Header right
+- `"bottom"` (default) - Bottom toolbar
+
+## Components
+
+### Button
+
+- Icon button: `<Stack.Toolbar.Button icon="star.fill" onPress={() => {}} />`
+- Text button: `<Stack.Toolbar.Button onPress={() => {}}>Done</Stack.Toolbar.Button>`
+
+**Props:** `icon`, `image`, `onPress`, `disabled`, `hidden`, `variant` (`"plain"` | `"done"` | `"prominent"`), `tintColor`
+
+### Menu
+
+Dropdown menu for grouping actions.
+
+```tsx
+<Stack.Toolbar.Menu icon="ellipsis">
+  <Stack.Toolbar.Menu inline>
+    <Stack.Toolbar.MenuAction>Sort by Recently Added</Stack.Toolbar.MenuAction>
+    <Stack.Toolbar.MenuAction isOn>
+      Sort by Date Captured
+    </Stack.Toolbar.MenuAction>
+  </Stack.Toolbar.Menu>
+  <Stack.Toolbar.Menu title="Filter">
+    <Stack.Toolbar.Menu inline>
+      <Stack.Toolbar.MenuAction isOn icon="square.grid.2x2">
+        All Items
+      </Stack.Toolbar.MenuAction>
+    </Stack.Toolbar.Menu>
+    <Stack.Toolbar.MenuAction icon="heart">Favorites</Stack.Toolbar.MenuAction>
+    <Stack.Toolbar.MenuAction icon="photo">Photos</Stack.Toolbar.MenuAction>
+    <Stack.Toolbar.MenuAction icon="video">Videos</Stack.Toolbar.MenuAction>
+  </Stack.Toolbar.Menu>
+</Stack.Toolbar.Menu>
+```
+
+**Menu Props:** All Button props plus `title`, `inline`, `palette`, `elementSize` (`"small"` | `"medium"` | `"large"`)
+
+**MenuAction Props:** `icon`, `onPress`, `isOn`, `destructive`, `disabled`, `subtitle`
+
+When creating a palette with dividers, use `inline` combined with `elementSize="small"`. `palette` will not apply dividers on iOS 26.
+
+### Spacer
+
+```tsx
+<Stack.Toolbar.Spacer />           // Bottom toolbar - flexible
+<Stack.Toolbar.Spacer width={16} /> // Header - requires explicit width
+```
+
+### View
+
+Embed custom React Native components. When adding a custom view make sure that there is only a single child with **explicit width and height**.
+
+```tsx
+<Stack.Toolbar.View>
+  <View style={{ width: 70, height: 32, justifyContent: "center" }}>
+    <Text style={{ fontSize: 12, fontWeight: 700 }}>Filter by</Text>
+  </View>
+</Stack.Toolbar.View>
+```
+
+You can pass custom components to views as well:
+
+```tsx
+function CustomFilterView() {
+  return (
+    <View style={{ width: 70, height: 32, justifyContent: "center" }}>
+      <Text style={{ fontSize: 12, fontWeight: 700 }}>Filter by</Text>
+    </View>
+  );
+}
+...
+<Stack.Toolbar.View>
+  <CustomFilterView />
+</Stack.Toolbar.View>
+```
+
+## Recommendations
+
+- When creating more complex headers, extract them to a single component
+
+```tsx
+export default function Page() {
+  return (
+    <>
+      <ScrollView>{/* Screen content */}</ScrollView>
+      <InboxHeader />
+    </>
+  );
+}
+
+function InboxHeader() {
+  return (
+    <>
+      <Stack.Screen.Title>Inbox</Stack.Screen.Title>
+      <Stack.SearchBar placeholder="Search" onChangeText={() => {}} />
+      <Stack.Toolbar placement="right">{/* Toolbar buttons */}</Stack.Toolbar>
+    </>
+  );
+}
+```
+
+- When using `Stack.Toolbar`, make sure that all `Stack.Toolbar.*` components are wrapped inside `Stack.Toolbar` component.
+
+This will **not work**:
+
+```tsx
+function Buttons() {
+  return (
+    <>
+      <Stack.Toolbar.Button icon="star.fill" onPress={() => {}} />
+      <Stack.Toolbar.Button onPress={() => {}}>Done</Stack.Toolbar.Button>
+    </>
+  );
+}
+
+function Page() {
+  return (
+    <>
+      <ScrollView>{/* Screen content */}</ScrollView>
+      <Stack.Toolbar placement="right">
+        <Buttons /> {/* ❌ This will NOT work */}
+      </Stack.Toolbar>
+    </>
+  );
+}
+```
+
+This will work:
+
+```tsx
+function ToolbarWithButtons() {
+  return (
+    <Stack.Toolbar>
+      <Stack.Toolbar.Button icon="star.fill" onPress={() => {}} />
+      <Stack.Toolbar.Button onPress={() => {}}>Done</Stack.Toolbar.Button>
+    </Stack.Toolbar>
+  );
+}
+
+function Page() {
+  return (
+    <>
+      <ScrollView>{/* Screen content */}</ScrollView>
+      <ToolbarWithButtons /> {/* ✅ This will work */}
+    </>
+  );
+}
+```
+
+## Limitations
+
+- iOS only
+- `placement="bottom"` can only be used inside screen components (not in layout files)
+- `Stack.Toolbar.Badge` only works with `placement="left"` or `"right"`
+- Header Spacers require explicit `width`

+# Visual Effects
+
+## Backdrop Blur
+
+Use `expo-blur` for blur effects. Prefer systemMaterial tints as they adapt to dark mode.
+
+```tsx
+import { BlurView } from "expo-blur";
+
+<BlurView tint="systemMaterial" intensity={100} />;
+```
+
+### Tint Options
+
+```tsx
+// System materials (adapt to dark mode)
+<BlurView tint="systemMaterial" />
+<BlurView tint="systemThinMaterial" />
+<BlurView tint="systemUltraThinMaterial" />
+<BlurView tint="systemThickMaterial" />
+<BlurView tint="systemChromeMaterial" />
+
+// Basic tints
+<BlurView tint="light" />
+<BlurView tint="dark" />
+<BlurView tint="default" />
+
+// Prominent (more visible)
+<BlurView tint="prominent" />
+
+// Extra light/dark
+<BlurView tint="extraLight" />
+```
+
+### Intensity
+
+Control blur strength with `intensity` (0-100):
+
+```tsx
+<BlurView tint="systemMaterial" intensity={50} />  // Subtle
+<BlurView tint="systemMaterial" intensity={100} /> // Full
+```
+
+### Rounded Corners
+
+BlurView requires `overflow: 'hidden'` to clip rounded corners:
+
+```tsx
+<BlurView
+  tint="systemMaterial"
+  intensity={100}
+  style={{
+    borderRadius: 16,
+    overflow: 'hidden',
+  }}
+/>
+```
+
+### Overlay Pattern
+
+Common pattern for overlaying blur on content:
+
+```tsx
+<View style={{ position: 'relative' }}>
+  <Image source={{ uri: '...' }} style={{ width: '100%', height: 200 }} />
+  <BlurView
+    tint="systemUltraThinMaterial"
+    intensity={80}
+    style={{
+      position: 'absolute',
+      bottom: 0,
+      left: 0,
+      right: 0,
+      padding: 16,
+    }}
+  >
+    <Text style={{ color: 'white' }}>Caption</Text>
+  </BlurView>
+</View>
+```
+
+## Glass Effects (iOS 26+)
+
+Use `expo-glass-effect` for liquid glass backdrops on iOS 26+.
+
+```tsx
+import { GlassView } from "expo-glass-effect";
+
+<GlassView style={{ borderRadius: 16, padding: 16 }}>
+  <Text>Content inside glass</Text>
+</GlassView>
+```
+
+### Interactive Glass
+
+Add `isInteractive` for buttons and pressable glass:
+
+```tsx
+import { GlassView } from "expo-glass-effect";
+import { SymbolView } from "expo-symbols";
+import { PlatformColor } from "react-native";
+
+<GlassView isInteractive style={{ borderRadius: 50 }}>
+  <Pressable style={{ padding: 12 }} onPress={handlePress}>
+    <SymbolView name="plus" tintColor={PlatformColor("label")} size={36} />
+  </Pressable>
+</GlassView>
+```
+
+### Glass Buttons
+
+Create liquid glass buttons:
+
+```tsx
+function GlassButton({ icon, onPress }) {
+  return (
+    <GlassView isInteractive style={{ borderRadius: 50 }}>
+      <Pressable style={{ padding: 12 }} onPress={onPress}>
+        <SymbolView name={icon} tintColor={PlatformColor("label")} size={24} />
+      </Pressable>
+    </GlassView>
+  );
+}
+
+// Usage
+<GlassButton icon="plus" onPress={handleAdd} />
+<GlassButton icon="gear" onPress={handleSettings} />
+```
+
+### Glass Card
+
+```tsx
+<GlassView style={{ borderRadius: 20, padding: 20 }}>
+  <Text style={{ fontSize: 18, fontWeight: '600', color: PlatformColor("label") }}>
+    Card Title
+  </Text>
+  <Text style={{ color: PlatformColor("secondaryLabel"), marginTop: 8 }}>
+    Card content goes here
+  </Text>
+</GlassView>
+```
+
+### Checking Availability
+
+```tsx
+import { isLiquidGlassAvailable } from "expo-glass-effect";
+
+if (isLiquidGlassAvailable()) {
+  // Use GlassView
+} else {
+  // Fallback to BlurView or solid background
+}
+```
+
+### Fallback Pattern
+
+```tsx
+import { GlassView, isLiquidGlassAvailable } from "expo-glass-effect";
+import { BlurView } from "expo-blur";
+
+function AdaptiveGlass({ children, style }) {
+  if (isLiquidGlassAvailable()) {
+    return <GlassView style={style}>{children}</GlassView>;
+  }
+
+  return (
+    <BlurView tint="systemMaterial" intensity={80} style={style}>
+      {children}
+    </BlurView>
+  );
+}
+```
+
+## Sheet with Glass Background
+
+Make sheet backgrounds liquid glass on iOS 26+:
+
+```tsx
+<Stack.Screen
+  name="sheet"
+  options={{
+    presentation: "formSheet",
+    sheetGrabberVisible: true,
+    sheetAllowedDetents: [0.5, 1.0],
+    contentStyle: { backgroundColor: "transparent" },
+  }}
+/>
+```
+
+## Best Practices
+
+- Use `systemMaterial` tints for automatic dark mode support
+- Always set `overflow: 'hidden'` on BlurView for rounded corners
+- Use `isInteractive` on GlassView for buttons and pressables
+- Check `isLiquidGlassAvailable()` and provide fallbacks
+- Avoid nesting blur views (performance impact)
+- Keep blur intensity reasonable (50-100) for readability

+# WebGPU & Three.js for Expo
+
+**Use this skill for ANY 3D graphics, games, GPU compute, or Three.js features in React Native.**
+
+## Locked Versions (Tested & Working)
+
+```json
+{
+  "react-native-wgpu": "^0.4.1",
+  "three": "0.172.0",
+  "@react-three/fiber": "^9.4.0",
+  "wgpu-matrix": "^3.0.2",
+  "@types/three": "0.172.0"
+}
+```
+
+**Critical:** These versions are tested together. Mismatched versions cause type errors and runtime issues.
+
+## Installation
+
+```bash
+npm install react-native-wgpu@^0.4.1 three@0.172.0 @react-three/fiber@^9.4.0 wgpu-matrix@^3.0.2 @types/three@0.172.0 --legacy-peer-deps
+```
+
+**Note:** `--legacy-peer-deps` may be required due to peer dependency conflicts with canary Expo versions.
+
+## Metro Configuration
+
+Create `metro.config.js` in project root:
+
+```js
+const { getDefaultConfig } = require("expo/metro-config");
+
+const config = getDefaultConfig(__dirname);
+
+config.resolver.resolveRequest = (context, moduleName, platform) => {
+  // Force 'three' to webgpu build
+  if (moduleName.startsWith("three")) {
+    moduleName = "three/webgpu";
+  }
+
+  // Use standard react-three/fiber instead of React Native version
+  if (platform !== "web" && moduleName.startsWith("@react-three/fiber")) {
+    return context.resolveRequest(
+      {
+        ...context,
+        unstable_conditionNames: ["module"],
+        mainFields: ["module"],
+      },
+      moduleName,
+      platform
+    );
+  }
+  return context.resolveRequest(context, moduleName, platform);
+};
+
+module.exports = config;
+```
+
+## Required Lib Files
+
+Create these files in `src/lib/`:
+
+### 1. make-webgpu-renderer.ts
+
+```ts
+import type { NativeCanvas } from "react-native-wgpu";

+
+## Basic 3D Scene
+
+```tsx
+import * as THREE from "three/webgpu";

+import { useRef } from "react";
+import { useFrame, useThree } from "@react-three/fiber";
+import { FiberCanvas } from "@/lib/fiber-canvas";
+
+function RotatingBox() {
+  const ref = useRef<THREE.Mesh>(null!);
+
+  useFrame((_, delta) => {
+    ref.current.rotation.x += delta;
+    ref.current.rotation.y += delta * 0.5;
+  });
+
+  return (

+
+## Lazy Loading (Recommended)
+
+Use React.lazy to code-split Three.js for better loading:
+
+```tsx
+import React, { Suspense } from "react";
+import { ActivityIndicator, View } from "react-native";
+
+const Scene = React.lazy(() => import("@/components/scene"));
+
+export default function Page() {

+    <View style={{ flex: 1 }}>
+      <Suspense fallback={<ActivityIndicator size="large" />}>
+        <Scene />
+      </Suspense>
+    </View>
+  );
+}

+// Box
+<mesh>
+  <boxGeometry args={[width, height, depth]} />
+  <meshStandardMaterial color="red" />
+</mesh>
+
+// Sphere
+<mesh>

+```
+
+## Lighting
+
+```tsx
+// Ambient (uniform light everywhere)
+<ambientLight intensity={0.5} />
+
+// Directional (sun-like)
+<directionalLight position={[10, 10, 5]} intensity={1} />
+
+// Point (light bulb)
+<pointLight position={[0, 5, 0]} intensity={2} distance={10} />
+
+// Spot (flashlight)
+<spotLight position={[0, 10, 0]} angle={0.3} penumbra={1} intensity={2} />
+```
+
+## Animation with useFrame
+
+```tsx
+import { useFrame } from "@react-three/fiber";
+import { useRef } from "react";
+import * as THREE from "three/webgpu";
+
+function AnimatedMesh() {
+  const ref = useRef<THREE.Mesh>(null!);
+
+  // Runs every frame - delta is time since last frame
+  useFrame((state, delta) => {
+    // Rotate
+    ref.current.rotation.y += delta;
+
+    // Oscillate position
+    ref.current.position.y = Math.sin(state.clock.elapsedTime) * 2;
+  });
+
+  return (
+    <mesh ref={ref}>
+      <boxGeometry />
+      <meshStandardMaterial color="orange" />
+    </mesh>
+  );
+}
+```
+
+## Particle Systems
+
+```tsx
+import * as THREE from "three/webgpu";
+import { useRef, useEffect } from "react";
+import { useFrame } from "@react-three/fiber";
+
+function Particles({ count = 500 }) {
+  const ref = useRef<THREE.Points>(null!);
+  const positions = useRef<Float32Array>(new Float32Array(count * 3));
+
+  useEffect(() => {
+    for (let i = 0; i < count; i++) {
+      positions.current[i * 3] = (Math.random() - 0.5) * 50;
+      positions.current[i * 3 + 1] = (Math.random() - 0.5) * 50;
+      positions.current[i * 3 + 2] = (Math.random() - 0.5) * 50;
+    }
+  }, [count]);
+
+  useFrame((_, delta) => {
+    // Animate particles
+    for (let i = 0; i < count; i++) {
+      positions.current[i * 3 + 1] -= delta * 2;
+      if (positions.current[i * 3 + 1] < -25) {
+        positions.current[i * 3 + 1] = 25;
+      }
+    }
+    ref.current.geometry.attributes.position.needsUpdate = true;
+  });
+
+  return (
+    <points ref={ref}>
+      <bufferGeometry>
+        <bufferAttribute
+          attach="attributes-position"
+          args={[positions.current, 3]}
+        />
+      </bufferGeometry>
+      <pointsMaterial color="#ffffff" size={0.2} sizeAttenuation />
+    </points>
+  );
+}
+```
+
+## Touch Controls (Orbit)
+
+See the full `orbit-controls.tsx` implementation in the lib files. Usage:
+
+```tsx
+import { View } from "react-native";
+import { FiberCanvas } from "@/lib/fiber-canvas";
+import useControls from "@/lib/orbit-controls";
+
+function Scene() {
+  const [OrbitControls, events] = useControls();
+
+  return (
+    <View style={{ flex: 1 }} {...events}>
+      <FiberCanvas style={{ flex: 1 }}>
+        <OrbitControls />
+        {/* Your 3D content */}
+      </FiberCanvas>
+    </View>
+  );
+}
+```
+
+## Common Issues & Solutions
+
+### 1. "X is not part of the THREE namespace"
+
+**Problem:** Error like `AmbientLight is not part of the THREE namespace`
+
+**Solution:** Add the missing component to the `extend()` call in fiber-canvas.tsx:
+
+```tsx
+extend({
+  AmbientLight: THREE.AmbientLight,
+  // Add other missing components...
+});
+```
+
+### 2. TypeScript Errors with Three.js
+
+**Problem:** Type mismatches between three.js and R3F
+
+**Solution:** Use `@ts-expect-error` comments where needed:
+
+```tsx
+// @ts-expect-error - WebGPU renderer types don't match
+await state.gl.init();
+```
+
+### 3. Blank Screen
+
+**Problem:** Canvas renders but nothing visible
+
+**Solution:**
+
+1. Ensure camera is positioned correctly and looking at scene
+2. Add lighting (objects are black without light)
+3. Check that `extend()` includes all components used
+
+### 4. Performance Issues
+
+**Problem:** Low frame rate or stuttering
+
+**Solution:**
+
+- Reduce polygon count in geometries
+- Use `useMemo` for static data
+- Limit particle count
+- Use `instancedMesh` for many identical objects
+
+### 5. Peer Dependency Errors
+
+**Problem:** npm install fails with ERESOLVE
+
+**Solution:** Use `--legacy-peer-deps`:
+
+```bash
+npm install <packages> --legacy-peer-deps
+```
+
+## Building
+
+WebGPU requires a custom build:
+
+```bash
+npx expo prebuild
+npx expo run:ios
+```
+
+**Note:** WebGPU does NOT work in Expo Go.

+# Apple Zoom Transitions
+
+Fluid zoom transitions for navigating between screens. iOS 18+, Expo SDK 55+, Stack navigator only.
+
+```tsx
+import { Link } from "expo-router";
+```
+
+## Basic Zoom
+
+Use `withAppleZoom` on `Link.Trigger` to zoom the entire trigger element into the destination screen:
+
+```tsx
+<Link href="/photo" asChild>
+  <Link.Trigger withAppleZoom>
+    <Pressable>
+      <Image
+        source={{ uri: "https://example.com/thumb.jpg" }}
+        style={{ width: 120, height: 120, borderRadius: 12 }}
+      />
+    </Pressable>
+  </Link.Trigger>
+</Link>
+```
+
+## Targeted Zoom with `Link.AppleZoom`
+
+Wrap only the element that should animate. Siblings outside `Link.AppleZoom` are not part of the transition:
+
+```tsx
+<Link href="/photo" asChild>
+  <Link.Trigger>
+    <Pressable style={{ alignItems: "center" }}>
+      <Link.AppleZoom>
+        <Image
+          source={{ uri: "https://example.com/thumb.jpg" }}
+          style={{ width: 200, aspectRatio: 4 / 3 }}
+        />
+      </Link.AppleZoom>
+      <Text>Caption text (not zoomed)</Text>
+    </Pressable>
+  </Link.Trigger>
+</Link>
+```
+
+`Link.AppleZoom` accepts only a single child element.
+
+## Destination Target
+
+Use `Link.AppleZoomTarget` on the destination screen to align the zoom animation to a specific element:
+
+```tsx
+// Destination screen (e.g., app/photo.tsx)
+import { Link } from "expo-router";
+
+export default function PhotoScreen() {
+  return (
+    <View style={{ flex: 1 }}>
+      <Link.AppleZoomTarget>
+        <Image
+          source={{ uri: "https://example.com/full.jpg" }}
+          style={{ width: "100%", aspectRatio: 4 / 3 }}
+        />
+      </Link.AppleZoomTarget>
+      <Text>Photo details below</Text>
+    </View>
+  );
+}
+```
+
+Without a target, the zoom animates to fill the entire destination screen.
+
+## Custom Alignment Rectangle
+
+For manual control over where the zoom lands on the destination, use `alignmentRect` instead of `Link.AppleZoomTarget`:
+
+```tsx
+<Link.AppleZoom alignmentRect={{ x: 0, y: 0, width: 200, height: 300 }}>
+  <Image source={{ uri: "https://example.com/thumb.jpg" }} />
+</Link.AppleZoom>
+```
+
+Coordinates are in the destination screen's coordinate space. Prefer `Link.AppleZoomTarget` when possible — use `alignmentRect` only when the target element isn't available as a React component.
+
+## Controlling Dismissal
+
+Zoom screens support interactive dismissal gestures by default (pinch, swipe down when scrolled to top, swipe from leading edge). Use `usePreventZoomTransitionDismissal` on the destination screen to control this.
+
+### Disable all dismissal gestures
+
+```tsx
+import { usePreventZoomTransitionDismissal } from "expo-router";
+
+export default function PhotoScreen() {
+  usePreventZoomTransitionDismissal();
+  return <Image source={{ uri: "https://example.com/full.jpg" }} />;
+}
+```
+
+### Restrict dismissal to a specific area
+
+Use `unstable_dismissalBoundsRect` to prevent conflicts with scrollable content:
+
+```tsx
+usePreventZoomTransitionDismissal({
+  unstable_dismissalBoundsRect: {
+    minX: 0,
+    minY: 0,
+    maxX: 300,
+    maxY: 300,
+  },
+});
+```
+
+This is useful when the destination contains a zoomable scroll view — the system gives that scroll view precedence over the dismiss gesture.
+
+## Combining with Link.Preview
+
+Zoom transitions work alongside long-press previews:
+
+```tsx
+<Link href="/photo" asChild>
+  <Link.Trigger withAppleZoom>
+    <Pressable>
+      <Image
+        source={{ uri: "https://example.com/thumb.jpg" }}
+        style={{ width: 120, height: 120 }}
+      />
+    </Pressable>
+  </Link.Trigger>
+  <Link.Preview />
+</Link>
+```
+
+## Best Practices
+
+**Good use cases:**
+- Thumbnail → full image (gallery, profile photos)
+- Card → detail screen with similar visual content
+- Source and destination with similar aspect ratios
+
+**Avoid:**
+- Skinny full-width list rows as zoom sources — the transition looks unnatural
+- Mismatched aspect ratios between source and destination without `alignmentRect`
+- Using zoom with sheets or popovers — only works in Stack navigator
+- Hiding the navigation bar — known issues with header visibility during transitions
+
+**Tips:**
+- Always provide a close or back button — dismissal gestures are not discoverable
+- If the destination has a zoomable scroll view, use `unstable_dismissalBoundsRect` to avoid gesture conflicts
+- Source view doesn't need to match the tap target — only the `Link.AppleZoom` wrapped element animates
+- When source is unavailable (e.g., scrolled off screen), the transition zooms from the center of the screen
