/* ===========================================================================
   Prompt Library — Homepage redesign (Framer "Miraculous Motivation")
   Component primitives only (buttons, cards, tags, badges). Section layout
   CSS lands with the index.njk rewrite (Phase 3). Palette tokens (--rd-*)
   live in styles.css under :root and :root.dark-theme.
   All classes are namespaced .rd-* so interior pages are unaffected.
