Changelog 2026-03-05 (Accessibility Nav List Semantics Pass 11)

Changed

• Converted main header navigation links to semantic list markup (ul/li) inside the existing nav landmark.
• Converted footer links to semantic list markup (ul/li) inside the footer nav landmark.
• Updated nav/footer CSS selectors to support list-based structure with no visual regressions.
• Preserved mobile snap ergonomics by applying mobile spacing/snap styles to .nav-list items.

Why

• Improves assistive-technology parsing of grouped navigation links and continues the accessibility sweep with structural semantics.
