/* IAlecole — feuille de style du hub (layout, sidebar, cartes, formulaires…).

 * Sortie de core/templates/core/base.html le 2026-10-06 (carnet #36 : 524
 * lignes de CSS recopiées dans CHAQUE page, jamais mises en cache). Les
 * variables (--lfis-blue…) restent déclarées dans core/_tokens.html, inclus
 * inline par base.html : une seule source pour les tokens, qui sert aussi aux
 * écrans plein écran (Lego, Ariane) sans passer par cette feuille.
 *
 * Cache : base.html ajoute ?v=<empreinte du fichier> (core.context.version_statique),
 * donc toute modification ici est vue au prochain chargement, sans vider le cache.
 * Déploiement : `collectstatic`, comme pour tout fichier statique.
