/* Audioguida cripta di Sant'Agnese in Agone
   Tema scuro e caldo, alto contrasto: si legge bene al buio e non abbaglia.
   Pensata per il telefono e per chi legge con fatica: nessun testo sotto i 16px,
   comandi principali da almeno 56px. Stile da guida a stampa: filetti al posto dei
   riquadri, didascalie in corsivo, l'oro solo per ciò che si tocca per ascoltare. */
