/* ============================================================
   AFL RULEBOOK — fresh redesign
   Scoped with rb- prefix; lives in its own stylesheet (loaded after
   style.css / darkmode.css) so the visual editor's style.css
   regeneration can't wipe it. Uses the site's design tokens so dark
   mode (neutral-ramp flip) is handled automatically; #fff is hardcoded
   only for white text sitting on the brand-red badges.
