   RUBY 1.01 — The Flourish Layer
   ───────────────────────────────────────────────────────────────
   Site-wide signature polish for Arcanist's Guidebook.
   Loaded AFTER theme.css and shell.css on every page.

   RULES
   • Tokens only — every colour references theme.css custom properties.
   • Additive only — no display/layout overrides of existing classes.
   • Pseudo-elements are used ONLY on ruby-/bran- prefixed classes,
     never hijacked on shared shell/module classes.
   • Everything animated is disabled under prefers-reduced-motion.
