Changelog 2026-03-07 (Phase 5: Accessibility Hardening Pass)

Published Mar 7, 2026 · Updated Mar 7, 2026

Changed

Upgraded shared home-tab behavior (/static/js/home-tabs.js) to use a stronger ARIA tab pattern:
- roving tabindex
- aria-controls wiring
- aria-hidden + tabindex panel sync
- keyboard support for ArrowLeft/Right/Up/Down, Home, and End
Added explicit tabindex + aria-controls defaults for homepage and projects tab buttons so no-JS state remains sane.
Introduced a reusable --focus-ring design token and normalized focus-visible outlines across links and form/button controls for more consistent keyboard visibility.

Improves keyboard predictability and focus order in tabbed UI surfaces.
Reduces ambiguity for assistive tech by tightening tab/panel relationships.
Raises visibility of focused interactive elements, especially in dense card-driven layouts.
