   (il gioco dell'oca ha una pagina a sé: static/css/oca.css)

   Tutto qui dentro viene dal manuale del marchio, edizione 01:
   due famiglie di colore e basta, tre voci tipografiche, misure
   multiple di 4. La regola che governa il resto è che il colore
   compare in quattro punti soli per pagina — il marchio, l'azione
   principale, i richiami di sezione e i dati. Il resto è carta e
   inchiostro: niente gradienti, niente ombre decorative.
