/* ============================================================
   lib-shell-template — canonical reference frontend lib navigable
   Drafté 2026-05-13 thread `ao-detector-frontend-lib-shell` round-3.

   CSS variables génériques au début (--surface-accent / --surface-r-* ...)
   → override dans :root de ton style.css pour appliquer ta palette.
   Tout le reste utilise ces variables, aucun hex hardcoded en composants.

   Référence sources canoniques (cultural-library, lecture-only) :
   - boardgame/style.css (pattern le + mature)
   - papers/style.css (text-card layout)
   - articles/stats.html (heatmap source × thème)
