/* ============================================================
   CYBERENTA — Login partagé (identique sur tous les modules)
   Source unique copiée dans chaque module (shared/css/auth-login.css).
   À lier APRÈS design-system.css. Tout est scopé sous .auth-page :
   n'affecte QUE la page de connexion, jamais les pages applicatives.
   La palette sombre est posée sur .auth-page (les variables cascadent
   vers .input/.btn/.form-label…), ce qui rend le login identique quel
   que soit le thème par défaut du module.
