/*
  Écrans d'authentification (connexion, vérification du second facteur).

  Parti pris : un écran de produit logiciel — fond en dégradé de halos repris
  des couleurs du logo, carte flottante centrée, champs à icône, bouton plein
  avec départ au survol. Feuille autonome : ces pages ne chargent ni Bootstrap
  ni rh.css, pour rester légères avant l'entrée dans l'outil.

  Pas de variante sombre : le logo est un trait noir sur fond transparent,
  qu'un aplat foncé effacerait. Le clair est donc assumé, pas subi.
