## Summary
- Fix broken markdown fences in `skills/a11y-debugging/SKILL.md` — a
stray quadruple-backtick on line 72 broke the numbered list
continuation, and a mismatched fence on line 95 disrupted rendering
- Extract verbose JS snippets (orphaned inputs, tap targets, color
contrast, global checks) into `references/a11y-snippets.md`, keeping
SKILL.md scannable and following the same `references/` pattern used by
`debug-optimize-lcp`
## Test plan
- [x] Verify SKILL.md renders correctly in GitHub markdown preview (no
broken fences or orphaned code blocks)
- [x] Verify `references/a11y-snippets.md` renders correctly and all 4
snippets are present
- [x] Confirm the relative links from SKILL.md to
`references/a11y-snippets.md` resolve correctly on GitHub
- **feat: Add Lighthouse audit as the initial step in the accessibility
debugging workflow and reorder subsequent sections.**
- **feat: Add critical instructions for parsing Lighthouse audit reports
to efficiently extract failing elements.**
