 * Ecrans d'authentification (connexion, inscription, mot de passe,

 * pilotent les accents.
 *
 * Contrainte : auth-form.js attend un <input> dans un .input-group lui-meme
 * dans un .form-group (il y ajoute le bouton oeil, l'alerte majuscules et la
 * jauge de robustesse) ; ce balisage est conserve tel quel.
