Feeds have unique accessibility challenges.
Focus management:
- When new posts load, don't steal focus
- Provide "skip to new content" option
- Maintain focus position during virtualization
Screen reader support:
- Announce new posts with aria-live
- Meaningful alt text for images
- Clear button labels (not just icons)
Keyboard navigation:
- Navigate between posts with arrow keys
- Enter to expand, Escape to collapse
- Shortcuts for like (L), comment (C), share (S)
Reduced motion: Respect prefers-reduced-motion for animations.
