   Vantage — site.css
   Design system della landing pubblica. Autonomo, nessun build step.

   Riferimento estetico: software strumentale serio (Linear, Height, Retool)
   riletto per chi gestisce commesse. Regole guida:
     · le superfici si separano con un filo di bordo, non con le ombre;
     · il blu del brand e' la voce dell'interfaccia; l'ambra dice «guarda qui»
       e compare pochissime volte, sempre su un numero che non va bene;
     · i numeri si scrivono in monospaziato, perche' sono dati e devono sembrarlo;
     · il movimento esiste solo per dimostrare il prodotto.
