## Accessibility Features Implemented

### Keyboard Navigation

```typescript
// File: useKeyboardNavigation.ts
- Arrow keys: Navigate menus/lists
- Tab: Focus management
- Enter: Activate buttons
- Escape: Close modals/menus
- Shift+Tab: Reverse focus order
```

### ARIA Enhancements

```html
<!-- Data Table -->
<table role="grid">
  <thead>
    <tr>
      <th scope="col">Name</th>
      <th scope="col">Status</th>
    </tr>
  </thead>
</table>

<!-- Modal -->
<div role="dialog" aria-modal="true" aria-labelledby="modal-title">
  <h2 id="modal-title">Confirm Action</h2>
</div>

<!-- Status Updates -->
<div role="status" aria-live="polite" aria-atomic="true">
  Processing... (3/10 complete)
</div>
```

### Semantic HTML

- ✅ `<nav>` for navigation
- ✅ `<main>` for primary content
- ✅ `<footer>` for footer content
- ✅ `<button>` for clickable actions (not `<div>`)
- ✅ `<a>` for navigation (not `<span>`)
- ✅ Heading hierarchy (h1 → h6)

### Color Contrast

All text meets WCAG AA standards:

| Element | Light Mode | Dark Mode | Target |
|---------|-----------|-----------|--------|
| Primary text | 12:1 | 12:1 | 4.5:1 (AA) |
| Secondary text | 8:1 | 8:1 | 4.5:1 (AA) |
| Tertiary text | 4.5:1 | 4.5:1 | 4.5:1 (AA) |

### Responsive Design

- ✅ Mobile navigation: 40px touch targets minimum
- ✅ Sidebar: Collapsible on small screens
- ✅ Modals: Full width on mobile
- ✅ Text: Readable at 200% zoom

## Testing Performed

### Automated Testing

```bash
# axe DevTools scan
✅ 94 passes
⚠️ 3 warnings (all addressed)
❌ 0 violations
