Accessibility Audit

Audit this page for accessibility: [URL or paste HTML].

Check and report, each with [PASS]/[FAIL] + the failing element:

1. Contrast — all text/background pairs incl. hover states and placeholders;
   flag anything under 4.5:1 (body) or 3:1 (large text/UI components).
2. Keyboard — tab order logical, focus visible (never outline:none without
   replacement), no keyboard traps, skip link present.
3. Semantics — one h1, heading order without skips, landmarks (header/nav/main/
   footer), lists as lists, buttons vs links used correctly.
4. Forms — every input labeled, errors announced (aria-describedby), required
   marked accessibly.
5. Images — alt text describes content (not "image of"), decorative images empty alt.
6. Motion — prefers-reduced-motion respected, nothing flashes > 3×/second.
7. Markdown twin — does the .md version preserve heading structure and link targets?

Deliverable: fixes ordered by user impact, each as a diff-style before/after snippet.
No rewrites of working markup.
