   Charte « premium » (passe design du 2026-09-30, demande d'Ams)
   Chargée après styles.css : elle redéfinit les jetons (couleurs, police, rayons,
   ombres) et l'habillage des composants communs. Pour revenir à l'ancien habillage,
   il suffit de retirer la ligne theme.css de index.html.

   - Police : Inter (hébergée dans /assets/fonts, 62 Ko, licence OFL).
   - Couleur d'accent : violet du logo de l'école. Les couleurs de notes restent
     orange < 50 %, gris < 70 %, bleu au-delà (maquette validée le 2026-09-26).
   - Menu clair, icônes au trait, surfaces blanches à filet fin, ombres très légères.
   - Transitions courtes (150–280 ms), coupées si le système demande moins d'animations.
