✅ ARIA used appropriately:

  • Landmarks: role="banner", role="navigation", etc.
  • Live regions: aria-live="polite", aria-live="assertive"
  • States: aria-current, aria-expanded, aria-selected
  • Labels: aria-label, aria-labelledby, aria-describedby

3. Focus Management

✅ Proper focus handling:

  • Focus moved to modal on open
  • Focus trapped within modal
  • Focus restored on close
  • Skip links provided

4. Keyboard Navigation

✅ Full keyboard support:

  • All functionality available via keyboard
  • Logical tab order
  • Arrow key navigation in lists
  • Enter/Space activate buttons

5. Dynamic Content

✅ Screen reader announcements:

  • New messages announced politely
  • Errors announced assertively
  • Loading states communicated
