Changelog 2026-03-05 (Accessibility Skip-Target Focus Pass 8)

Changed

• Added scroll-margin-top to #main-content so skip-link jumps don’t land under the sticky header.
• Added explicit :focus-visible outline styling for #main-content so keyboard users can clearly see skip-link landing state.

Why

• Improves keyboard navigation clarity and makes the skip-link flow more robust on sticky-header layouts.
