/* ─────────────────────────────────────────────────────────────
   NAVIGAZIONE CONDIVISA — una sola fonte di verità per tutte le pagine.
   - Base: nav solida (pagine interne).
   - .nav--overlay: variante trasparente sopra l'hero (home), che diventa
     solida quando si scrolla (classe .scrolled aggiunta da js/nav.js).
   - Mobile (<=860px): hamburger + drawer accessibile.
   Le voci restano IDENTICHE e nella stessa posizione su ogni pagina.
