Changelog 2026-03-05 (Accessibility Time + Byline Semantics Pass 12)

Changed

• Added semantic <time datetime> markup to homepage date metadata in latest-posts, latest-changelog, recent-entry rows, and latest-ship metadata.
• Updated author-bio partial landmark labeling from generic aria-label to heading association (aria-labelledby).
• Added explicit author relation/context on profile links (rel="author" + descriptive aria-label).

Why

• Improves assistive-tech parsing of temporal metadata and clarifies byline/profile relationships without changing page layout.
