   --------------------------------------------------------
   FONT   : Montserrat Regular + Italic. Per cambiare font
            sostituisci i nomi dei file nelle 2 righe @font-face
            qui sotto (cartella assets/fonts/). Il nome
            "BOX21 Font" NON va cambiato.
   COLORI : cambia solo i codici HEX nel blocco :root
            (es. #D6D2C4). Tutto il sito si aggiorna da solo.
   LOGO   : sostituisci il file Logo_steso.png, oppure cambia
            larghezza e filtro nel blocco :root.
