   Design tokens — "liquid glass" tech: bianco, bianco ghiaccio, viola tech.
   Pannelli traslucidi con backdrop-blur sopra uno sfondo con blob sfumati
   animati; un solo accento (viola) usato come gradiente per azioni
   primarie e testo in evidenza. Companion scuro reale (viola-notte, non
   un semplice invert) per chi ha il sistema in dark mode.
