### Testing environment
Automated: axe-core, headless Chromium (Playwright). Manual AT verification: Not captured by automated scan — requires manual testing.

### Suggested fix
**How to fix:** When a landmark role/type repeats (e.g. two <nav>s), give each a distinct accessible name with aria-label or aria-labelledby (e.g. "Primary" and "Footer" navigation) so screen-reader users can tell them apart.
