## Accessibility

### Screen Reader:

---

## Performance Considerations

### CSS:
- No JavaScript required for responsive layouts
- Pure CSS media queries
- Minimal specificity conflicts

### Images:
- `loading="lazy"` on below-fold images
- `decoding="async"` for non-blocking render
- Explicit `width` and `height` attributes

---

## Browser Compatibility

### Tested/Supported:
- ✅ Chrome/Edge (latest)
- ✅ Firefox (latest)
- ✅ Safari (iOS 12+, macOS)
- ✅ Samsung Internet
- ✅ Mobile Chrome (Android)

### Fallbacks:
- Original responsive rules preserved as fallback
- `@supports` not required (basic CSS features)

---

## Known Limitations

1. **iOS Safari Address Bar**: Bottom nav may overlap with address bar when scrolling. Mitigated with `padding-bottom: env(safe-area-inset-bottom)`.

2. **Landscape Video**: On very small devices (≤375px width), video player may dominate viewport. Users should rotate to portrait for optimal viewing.

3. **Long Tags/Words**: Tags with very long text may wrap awkwardly on ≤375px. Consider adding `word-break: break-word` if needed.
