/* =====================================================================
   FROST STUDIO — section (05) « Le Bureau » (bureau.css)
   La conclusion du site : le bureau d'Axel, la nuit, deux écrans allumés.
   La scène est une boucle vidéo (écrans générés vides) ; nos interfaces
   vivantes sont posées en perspective sur les dalles (`matrix3d` calculée
   par bureau.js) : à gauche le mur des sites, à droite la prise de
   rendez-vous. Un clic sur un écran approche la caméra (le cadre entier
   est mis à l'échelle autour de l'écran) ; « Retour au bureau » recule.
   Mobile : la scène en image, la prise de rendez-vous en dessous.
