/* ───────────────────────────────────────────────────────────
   Cyboflow site — Changelog page
   Sits on tokens.css + site.css. A reading-column release
   timeline: hero + "synced from source" bar, sticky change-type
   filter, and a vertical spine of releases grouped by kind.
   Paper aesthetic — hairline borders, square corners, one rust
   accent, the design system's per-kind colors (Added=green,
   Fixed=rust, Changed=gold).
