## Recommendations for Week 6

### Critical (Must Address)
None — no critical issues detected. All WCAG 2.1 AA criteria met.

### Important (Should Address)
1. **Contact Form Keyboard** — Form submission can be keyboard-only (already implemented)
2. **About Page Heading Hierarchy** — Ensure h2 used after h1, no skipped levels
3. **404 Page Navigation** — Provide clear navigation back to home (keyboard accessible)

### Nice to Have (Enhancement Opportunities)
1. **Skip Link** — Already implemented; could be more prominent on focus
2. **Extended Screen Reader Testing** — Test with JAWS (Windows), additional screen readers
3. **Mobile A11y Testing** — Extended testing on physical devices (not just emulation)
4. **Automated Testing** — Implement automated accessibility checks (axe-core, etc.)
