/* ═══════════════════════════════════════════════════════════════
   ATLAS — shared design layer (student app + admin dashboard)
   A course is a route. Information sits on plates that point at their stop,
   the next action is one round "go" button, and state is a marker on the map.
   • The only colour that changes per school is --brand (Settings → Branding);
     it drives the go button, the route line and the "you are here" marker.
   • Everything is logical (inline-start / inline-end) so right-to-left layouts mirror.
   • Student pages run under a strict CSP: own fonts, own styles, no inline <style>.
