# Accessibility

Target WCAG 2.2 Level AA.

## Required practices

- Semantic HTML.
- Full keyboard access.
- Visible focus indicators.
- Logical focus order.
- Accessible names for controls.
- Labels for all form inputs.
- Required/optional state communicated programmatically and visually.
- Accessible validation and error messages.
- No color-only meaning.
- Sufficient contrast.
- Responsive layouts.
- Support browser zoom and text resizing.
- Accessible dialogs and galleries.
- Focus management for dynamic UI.
- Appropriate live-region/status announcements for important asynchronous changes.
- Meaningful image alt text.
- Use ARIA only where native semantics are insufficient.

## Testing

Run automated accessibility testing in CI.

Serious accessibility regressions should fail CI.

Automated tests do not replace manual keyboard and assistive-technology review for important workflows.
