Accessibility Audit

Workflow

Detect framework from package.json (React, Vue, Svelte)
Run static analysis -- grep JSX/TSX/HTML files for violations
If dev server is running, optionally run axe-core CLI:
```
npx @axe-core/cli@4 http://localhost:3000
```
Report findings grouped by severity

Output format

Group by WCAG criterion:

Critical (A) -- blocks assistive technology users
Serious (AA) -- significantly impacts usability
Suggestions -- best practice improvements

Use file:line references. Include the fix for each finding. Prioritize keyboard navigation and screen reader issues; never auto-fix -- show what to change and why.

Error Handling

Framework undetected -- scan all .html, .jsx, .tsx, .vue files
