   ---------------------------------------------------------------------------
   Reading this as: trust-first consumer booking for Egyptian students, calm
   editorial-modern, one warm accent against deep pine ink.

   Rules this file enforces:
   - ONE accent (terracotta). Everything else is pine/ink/sand neutrals.
   - ONE radius scale: 4px (inputs/tags) / 10px (cards) / 999px (pills only).
   - Light + dark from the same tokens, both tuned for WCAG AA.
   - Motion only on transform/opacity, all of it disabled under
     prefers-reduced-motion.
