   PAGE DE CONNEXION — Dental Clinic Manager
   Idée : la page s'ouvre sur une arcade dentaire. Le formulaire est placé
   « dans la bouche », sous l'arc des dents. Une seule animation : les dents
   apparaissent du centre vers le fond au chargement.
   Préfixe .lg- : aucun conflit avec les autres pages.
