## Examples

**Input:** Review design for accessibility
**Output:**
```markdown
### Accessibility Review

**Overall Compliance:** WCAG 2.1 Level AA ✓

**Color Contrast:**
- Primary text on white: 4.5:1 ✓ (WCAG AA)

- **Missing Alt Text**: Images without descriptive alt text
- **Missing Labels**: Form inputs without labels
- **Small Touch Targets**: Interactive elements too small
- **No Focus Indicators**: Missing visible focus states
