/* ═══════════════════════════════════════════════════════════════════
   library.css — the one shared stylesheet for books.mbuhamad.com
   (and books2, which copies it via generate_static.py MAP_ASSETS).

   Load it BEFORE a page's own <style>, so page rules still win:
     <link rel="stylesheet" href="/library.css?v=1">
   Bump ?v= on every change (Cloudflare caches .css).

   Rules (2026-10-26):
   - Colours come from these tokens only. A page that needs a new
     colour adds a token here, not a hex in its own <style>.
   - Text colour on any surface must reach 4.5:1 (WCAG AA).
     --muted #9090b4 is ≥4.8:1 on every background below, incl. --border.
     --gold-dim is for fills/borders/gradients, never for text.
   - Smallest type is --fs-xs (11px). Nothing smaller, badges included.
   - Components are prefixed lb- so they never collide with page classes.
