### Manual Testing
1. Navigate entire site using only keyboard
2. Use screen reader for critical flows
3. Zoom to 200% and check layout
4. Disable CSS and check content order
5. Test with reduced motion preference

## Common Issues & Fixes

### Missing Alt Text
```tsx
// Bad
<img src="hero.jpg" />

// Good
<img src="hero.jpg" alt="FrankX creating music in studio" />

// Decorative
<img src="decorative-wave.svg" alt="" role="presentation" />
```

### Poor Focus Styles
```css
/* Bad - removes focus indicator */
*:focus { outline: none; }

/* Good - custom but visible */
*:focus-visible {
  outline: 2px solid var(--focus-color);
  outline-offset: 2px;
}
```

### Missing Form Labels
```tsx
// Bad
<input type="email" placeholder="Email" />

// Good
<label htmlFor="email">Email address</label>
<input type="email" id="email" />
```

### Color-Only Information
```tsx
// Bad - relies only on color
<span className="text-red-500">Error</span>

// Good - includes icon/text
<span className="text-red-500">
  <ErrorIcon aria-hidden /> Error: Invalid email
</span>
```
