/* ============================================================
   RaiseMeTop — Design System

   Learner-first, indigo. Light surfaces, one sans stack, generous
   whitespace, a single headline hero and three large low-saturation
   entry tiles. No web fonts and no CDN: everything resolves to system
   families so the site stays self-contained.
   Legacy palette names (--gold / --navy / --ivory / --cream) are kept
   as aliases onto the indigo system so existing components stay
   consistent. No component uses a single thick side border.
