/* auth.css — Socle commun des pages publiques d'authentification
   (login, signup, forgot-password, reset-password, verify-email).
   Source de vérité unique de la DA auth : thème light/dark, carte, champs,
   boutons satin, blocs erreur/succès. Toute couleur passe par une variable
   de thème — jamais de couleur claire figée qui casserait le mode sombre.
   Le socle motion (durées, easings, reduced-motion, focus-visible) vient de
   shared.js ; la taille de police de base (html 20/23/26px) aussi. */
