Key Implementations

1. Interactive Components

• Buttons: data-testid, aria-label, proper role attributes
• Forms: data-testid, aria-label, aria-invalid, aria-describedby
• Dropdowns: data-testid, aria-haspopup, aria-expanded
• Dialogs: data-testid, role="dialog", aria-modal

2. Semantic Structure

• Regions: role="region" with aria-label
• Navigation: role="navigation" on nav elements
• Status: role="status", aria-live="polite/assertive"
• Alerts: role="alert" for important messages

3. Accessibility States

• Loading: aria-busy="true", role="status"
• Selection: aria-selected, aria-current
• Validation: aria-invalid, error descriptions
• Expansion: aria-expanded for collapsible sections

4. Visual vs. Semantic

• Decorative: aria-hidden="true" on non-essential icons
• Alt text: Image components properly labeled
• Skip links: Navigation helpers implemented

Next Steps (Optional)

1. Accessibility Audit: Run automated audit tools (axe, WAVE)
2. Manual Testing: Test with screen readers (NVDA, JAWS, VoiceOver)
3. Keyboard Navigation: Verify tabindex and focus order
4. E2E Tests: Write tests using data-testid selectors
5. Performance: Monitor bundle size (negligible impact)
