## Technical Notes
- Use `.accessibilityLabel()` and `.accessibilityHint()` modifiers
- Check `UIAccessibility.isReduceMotionEnabled` for animations
- Use `@ScaledMetric` for Dynamic Type-responsive sizing
- Test with VoiceOver, Voice Control, and Switch Control

## Edge Cases
- Complex canvas gestures: provide alternative VoiceOver actions
- Image descriptions: consider describing detected content for blind users
- Color-only indicators: always pair with shape or text
