/* ============================================================================
   Release / build-record pages (/releases/*)

   Loaded per-page via `extraCss` in src/releases/releases.json, so the weight
   never lands on the marketing pages. Everything here is scoped under `.rd`
   and built from the redesign token set (redesign.css :root), so a release
   page inherits the site's palette, type scale, and motion rather than
   introducing a second design language.
