/* ---------------------------------------------------------------------------
   Mondi Radio — foglio di stile del sito.

   Due temi, gli stessi nomi del programma:
     · Chiaro — quello di partenza: bianco con gli accenti viola e corallo
                dell'icona. È quello che si vede all'arrivo e anche senza JavaScript.
     · Cosmo  — i colori dell'icona: la notte indaco, il viola e il magenta
                della sfera, il corallo che entra dall'angolo. Col pulsante in alto.

   I colori stanno tutti e soli nelle due liste qui sotto. Il resto del foglio
   non nomina mai un colore: usa le variabili.

   Il carattere è Inter, servito da qui (assets/fonts, quattro pesi, sottoinsieme
   latino): nessuna richiesta a server di terzi. Le lingue che Inter non copre
   (giapponese, coreano, cinese) usano il carattere del sistema.
