   QUESTION.MA — Système de design
   Concept : le tableau noir et le stylo rouge — l'expérience
              d'un examen corrigé sur-le-champ, pas un badge SaaS.
   Palette : Tableau (vert ardoise), Stylo Rouge, Craie, Encre Douce
   Typo     : Bricolage Grotesque (une seule famille, 2 graisses)
              + JetBrains Mono pour les données (scores, chrono, codes)
   Signature: "La Coche" — la coche au stylo rouge qui corrige une copie.
