## Symptom
Models still write `import { Audio, Video } from 'expo-av'` with `Audio.Sound.createAsync()` and `<Video source=... useNativeControls />`. On SDK 55+ this does not run in Expo Go, and in development builds expo-av gets no patches and may stop working.

## Cause
- SDK 53 (2025-04-30) deprecated expo-av: its Video component was replaced by `expo-video`, and `expo-audio` became the recommended audio library. No new expo-av versions are published for SDK 54+.
- SDK 54 (2025-09-10) was the last SDK that included expo-av.
- SDK 55 (2026-02-25) removed expo-av from Expo Go.

## Fix
```bash
npx expo install expo-audio expo-video
npm rm expo-av
```
Audio:
```tsx
// before
const { sound } = await Audio.Sound.createAsync(require('./assets/hello.mp3'))
await sound.playAsync()

// after
import { useAudioPlayer } from 'expo-audio'
const player = useAudioPlayer(require('./assets/hello.mp3'))
// <Button title="Play" onPress={() => player.play()} />
// replay: player.seekTo(0); player.play()
```
Video:
```tsx
import { useVideoPlayer, VideoView } from 'expo-video'

const player = useVideoPlayer(videoSource, (p) => { p.loop = true; p.play() })
return <VideoView player={player} style={{ width: 350, height: 275 }} fullscreenOptions={{ enable: true }} allowsPictureInPicture />
```
In SDK 55 the `allowsFullscreen` prop of `VideoView` was removed; use `fullscreenOptions={{ enable: true }}`.

## Verify
`npm ls expo-av` is empty, and playback works in a development build (and in Expo Go on SDK 55+).
