## 📊 Bundle Size

- Core library: **~8KB** (gzipped)
- HLS.js (optional, lazy-loaded): **~200KB** (only when using HLS streams)

## 🔧 Technical Details

### Native Browser APIs Used
- HTML5 Video API
- Fullscreen API
- Picture-in-Picture API
- Media Session API
- Fetch API (Range Requests)
- Touch Events API
- Keyboard Events API

### Streaming Support

**MP4/WebM (Progressive Download)**
- Uses HTTP Range Requests
- Browser automatically chunks the download
- No additional library needed
- Works with any standard web server that supports Range headers

**HLS (.m3u8)**
- Automatically detects HLS sources
- Lazy loads hls.js library when needed
- Safari has native HLS support (no library needed)
- Adaptive bitrate streaming

### Performance Optimizations
- Lazy loading of HLS.js with CDN fallback
- CSS-only animations
- Debounced control hiding
- Optimized re-renders with React.memo
- Tree-shakeable exports
- Memory leak prevention with proper cleanup
- Polyfills for older browser support

### Error Handling & Reliability
- **CORS Detection**: Automatically detects and reports CORS issues with helpful error messages
- **HLS.js Fallback**: If npm package fails to load, automatically falls back to CDN
- **Memory Management**: Proper cleanup of HLS instances to prevent memory leaks
- **Browser Polyfills**: Vendor prefix support for Fullscreen and PIP APIs
- **URL Validation**: Validates video URLs before attempting to load
- **Feature Detection**: Checks browser capabilities before using advanced features

## 🚧 TODO / Future Enhancements
