   Cashflow — design tokens
   Concept: registro contabile digitale. Sfondo "inchiostro" profondo,
   accento ottone per i richiami di valore, monospace per ogni cifra e data
   (leggibilità in colonna, come un vero libro mastro). Entrate/uscite hanno
   colori dedicati usati SOLO per quello, mai come decorazione.
