   NectaPlanner — site.css
   Design system della landing pubblica. Autonomo: NON dipende da base.css
   né da v1…v4.css (che restano in vita solo per le vecchie varianti in /v1…/v4).

   Riferimento estetico: software strumentale serio (Linear, Height, Retool)
   riletto per un pubblico industriale. Regole guida:
     · le superfici si separano con un filo di bordo, non con le ombre;
     · un solo accento acceso, usato poche volte e sempre per chiedere un'azione;
     · i numeri si scrivono in monospaziato, perché sono dati e devono sembrarlo;
     · il movimento esiste solo per dimostrare il prodotto.
