/* ─────────────────────────────────────────────────────────────────────────
   Design system delle pagine interne (/aziende/, /upsell/).

   E' lo stesso identico linguaggio visivo della home (index.html): stesse
   variabili, stessi font, stessi bottoni. Qui sta in un file a parte e non
   inline come nella home perche' due pagine lo condividono: duplicarlo
   avrebbe voluto dire mantenerlo in due posti e vederlo divergere.
   Nessuna dipendenza esterna oltre a Google Fonts, gia' usato dalla home.
