/* ============================================================
   MutuoClick — Cornice di pagina (shell): header, navbar, footer, main.
   Resa server-side da Twig, caricata su tutte le pagine (base.html.twig).

   ⚠ Gli stili del WIDGET comparatore (wizard, stepper, card di confronto,
   variante dark, hardening responsive) NON stanno più qui: vivono nel plugin
   `comparatore-mutui` (css/comparatore.css), che li carica solo dove il
   widget è presente. Qui resta solo la cornice del tema.
   Tutti i valori sono token (css/tokens.css) — niente hardcoding.
