   Sorgente unica dei token. Nessuna pagina deve piu' dichiarare
   il proprio :root: se un colore non e' qui, non esiste.

   Direzione: quotidiano dei numeri. Carta neutra, inchiostro
   quasi nero, filetti al posto delle ombre, numeri in mono
   tabellare. L'ottone e' un sigillo, non una vernice: si usa
   SOLO per il valore. Mai per decorare.
