/* ===========================================================================
   Educatex — feuille de style

   Direction : le cahier d'école romand. Papier légèrement chaud, encre
   bleu-noir, quadrillage discret sur le fond de l'application. Le rouge est
   réservé aux erreurs et aux corrections — jamais à la décoration, jamais à un
   bouton d'action. C'est la seule règle chromatique qui ne se négocie pas :
   dans une interface scolaire, le rouge veut dire quelque chose.

   Aucune police distante : l'isolation d'origine bloque les CDN, et un
   établissement n'a pas à voir ses requêtes partir chez un tiers.
