 * base.css — styles communs à toutes les pages du site.
 *
 * Chaque page charge base.css, puis éventuellement sa feuille propre :
 *   accueil.css (accueil), solutions.css (infrastructure, opérateur, cloud, erp),
 *   recrutement.css (recrutement et offres), support.css, legal.css (pages légales).
 * Une règle utilisée par une seule famille de pages va dans sa feuille propre, pas ici.
 *
 * Sommaire
 *   1. Variables, éléments HTML et composants communs
 *      (barre du haut, en-tête, menu, boutons, titres de section, bandeau d'appel,
 *       fil d'Ariane, pied de page, fenêtre de contact et formulaire)
 *   2. Messages d'envoi des formulaires (assets/formulaires-ajax.js)
 *   3. Accessibilité — en dernier pour rester prioritaire (focus visible, lien
 *      « Aller au contenu », réduction des animations)
