# Accessibility Check

Perform a WCAG 2.1 AA compliance audit on frontend components.

## Audit Areas

### 1. Keyboard Navigation
- All interactive elements must be focusable
- Tab order must be logical
- No keyboard traps
- Visible focus indicators (use `.focus-ring`)

### 2. Screen Reader Support
Search for issues:
```bash
# Icon-only buttons missing aria-label
grep -rE "<Button[^>]*>[^<]*<svg" frontend/src/components/ --include="*.tsx" | grep -v "aria-label"

# Images missing alt text
grep -r "<img" frontend/src/components/ --include="*.tsx" | grep -v "alt="

# Missing form labels
grep -rE "<input[^>]*>" frontend/src/components/ --include="*.tsx" | grep -v "aria-label\|id.*label"
```

### 3. Color Contrast
Pierre design system colors meet contrast requirements:
- `pierre-gray-900` on white: 15.3:1 ✓
- `pierre-gray-700` on white: 8.5:1 ✓
- `pierre-gray-500` on white: 4.6:1 ✓ (minimum for large text)
- `pierre-violet` on white: 5.7:1 ✓

**Flag if using**:
- `pierre-gray-400` for body text (3.0:1 - FAILS)
- Light colors on light backgrounds
- Custom colors not in design system

### 4. Touch Targets
- Minimum 44x44px for touch targets
- Check Button `size="sm"` usage - ensure adequate padding

### 5. Motion & Animation
- Respect `prefers-reduced-motion`
- No auto-playing animations that distract
