/* ===========================================================================
   BioFrame — sistema visivo del sito pubblico.
   Tema scuro continuo: la pagina non cambia mai registro, dall'apertura al
   piè di pagina. Le sezioni si distinguono per profondità, non per colore.

   Caratteri
   - Space Grotesk: titoli, navigazione, numeri. Nasce da un carattere
     monospazio: ha la precisione di uno strumento di misura, che è
     esattamente il mestiere di questo prodotto.
   - Manrope: testo corrente, per leggibilità nei paragrafi lunghi.
   - Fraunces corsivo: la parola accentata nei titoli.
