/* ============================================================
   Changelog — shared timeline styling
   Single source of truth for BOTH the static fallback page
   (public/changelog-static.html) and the dynamic Firestore-rendered
   page (g8ChangelogRenderer at /changelog). Anti-doublon: edit here once.

   Dark glassmorphic timeline. Brand orange accents. One pill visual
   language. Mobile-first responsive. Hover states. Co-creation
   gratitude voice (Sprint 5.A memory rule).

   2026-06-09 density pass (founder: "trop gros, 100% on voit rien"):
   tightened paddings / margins / type so far more ships are visible
   per viewport without zooming out. Look preserved, scale reduced.
