   Documentazione (/docs/): stesso linguaggio del sito, nessun colore, font o componente nuovo.
   Variabili e componenti riusati da style.css / pages.css / sub.css (.support-hero, .support-search, .link-list,

   Colori del sito: testo #1d1d1f, secondario #424245, attenuato #6e6e73, tenue #86868b, linee #d2d2d7,
   fondo alternato #f5f5f7, link var(--link), arancio dei badge #bf4800.
