   Sistema condiviso — chrome (font, token, header/nav, footer) e tipografia
   di pagina, usati da tutte le pagine pubbliche (home esclusa per l'hero,
   che resta inline in index.html perché non riusata altrove).
   Header e footer sono comunque markup duplicato a mano in ogni pagina
   (nessun sistema di partial, per restare senza build): quando cambi
   .site-header, .site-nav, .lang-switch, .nav-panel o .site-footer qui,
   aggiorna lo stesso markup in TUTTE le 15 pagine pubbliche —
   italiano:  index.html, chi-siamo/, eventi/, contatti/, trasparenza/,
              statuto/, privacy.html, 404.html
