## Key Implementations

### 1. Interactive Components
- **Buttons**: `data-testid`, `aria-label`, proper `role` attributes
- **Forms**: `data-testid`, `aria-label`, `aria-invalid`, `aria-describedby`
- **Dropdowns**: `data-testid`, `aria-haspopup`, `aria-expanded`
- **Dialogs**: `data-testid`, `role="dialog"`, `aria-modal`

### 2. Semantic Structure
- **Regions**: `role="region"` with `aria-label`
- **Navigation**: `role="navigation"` on nav elements
- **Status**: `role="status"`, `aria-live="polite/assertive"`
- **Alerts**: `role="alert"` for important messages

### 3. Accessibility States
- **Loading**: `aria-busy="true"`, role="status"
- **Selection**: `aria-selected`, `aria-current`
- **Validation**: `aria-invalid`, error descriptions
- **Expansion**: `aria-expanded` for collapsible sections

### 4. Visual vs. Semantic
- **Decorative**: `aria-hidden="true"` on non-essential icons
- **Alt text**: Image components properly labeled
- **Skip links**: Navigation helpers implemented

## Next Steps (Optional)

1. **Accessibility Audit**: Run automated audit tools (axe, WAVE)
2. **Manual Testing**: Test with screen readers (NVDA, JAWS, VoiceOver)
3. **Keyboard Navigation**: Verify tabindex and focus order
4. **E2E Tests**: Write tests using data-testid selectors
5. **Performance**: Monitor bundle size (negligible impact)
