/*
 * Page de connexion — profondeur et relief.
 *
 * Le reste du CRM utilise deja un vocabulaire de relief : cartes qui
 * s'inclinent sous le pointeur, halos colores, grille de fond. La page de
 * connexion restait plate et sans logo. Elle reprend ici le meme vocabulaire,
 * avec une scene en perspective dont les plans se decalent a des vitesses
 * differentes selon la position du pointeur — c'est ce decalage, et non une
 * rotation seule, qui donne la sensation de profondeur.
 *
 * Toute l'animation est pilotee par deux variables, --px et --py, comprises
 * entre -1 et 1. Sans JavaScript, elles valent zero et la page reste
 * parfaitement utilisable : le relief est un supplement, jamais une condition.
