/* ── Changelog (/changelog) ────────────────────────────────────────────────
   Loaded ON TOP of legal.css, which already provides the page frame this
   shares with About / Privacy / Terms: the document column, the hero, the
   sidebar table of contents and its scrollspy. Everything here is the release
   timeline and nothing else — putting the frame in a fourth file is how the
   legal pages would start drifting apart.

   All colours are theme.css tokens, so the page is written once and reads
   correctly in both palettes. Note --hi-rgb below: it flips MEANING rather than
   value between themes (white on dark, near-black on light), which is what
   makes one hairline rule work in both. */

/* ── Version index (sidebar) ──
   legal.css sizes .legal-toc-num for a two-digit section number ("01"). A
   version prefix ("1.34") is wider, so the chip has to grow or the release
   titles beside it are ragged. */
