   ═══════════════════════════════════════════════════════════════════════════
   Feuille commune aux parcours client et admin, d'apres les maquettes Figma.
   Deux themes, une seule structure :

     .auth--client   carte centree, bleu Hopwise   #e5322d
     .auth--admin    pleine page, sans carte, bleu profond #2c2e34

   Regrouper ici evite de recopier ces regles dans les six <head> concernes,
   et garantit que les six pages evoluent ensemble.
