Changelog 2026-03-04 (Accessibility Foundation Pass 1)

Changed

• Added a visible-on-focus Skip to content link at the top of every page.
• Added id="main-content" and tabindex="-1" to the main landmark so skip-link navigation lands correctly.
• Added aria-current="page" on active navigation links for better screen reader context.
• Added explicit :focus-visible styles for the theme toggle button to improve keyboard discoverability.

Why

• Start the accessibility sweep with high-impact, low-risk improvements for keyboard and assistive-technology navigation.
