   ATRP — linguaggio visivo 3D del sito principale
   Caricato SOLO dalle pagine del sito (dopo styles.css e motion.css): il CAD non lo usa.
   Materiali con spessore e luce, inclinazione prospettica, livelli a profondità diverse,
   composizioni 3D (veicolo, CAD, rete del bot, smartphone, galleria, mappa di Los Angeles).
   Palette invariata: blu #1b97e3, bianco, blu notte; nessun colore nuovo.
   Movimento: solo transform/opacity; tutto si spegne con prefers-reduced-motion (motion.css).
