Changelog 2026-03-05 (Accessibility Changelog Filter Tab Pattern Pass 15)

Changed

• Updated changelog filter controls to use a tablist pattern (role="tablist" + role="tab").
• Replaced pressed-state attributes with selected-state semantics (aria-selected) and active/inactive tabindex values.
• Updated keyboard behavior so Arrow/Home/End moves both focus and active filter, with Enter/Space activation support.

Why

• Better matches assistive-tech expectations for mutually exclusive category switches.
• Improves keyboard-only navigation by keeping focus and active state synchronized.
