/* Lo sfondo sfumato (backdrop-filter) NON sta sull'header stesso ma

   nel "contenitore di riferimento" per i figli con position:fixed,
   incluso il menu mobile #nav — che a quel punto smetterebbe di
   ancorarsi a tutto lo schermo e si schiaccerebbe nell'altezza
   dell'header stesso, restando visibile solo a pezzi. E' esattamente
   il bug segnalato da Helena il 2026-09-23 su iPhone/Safari: il menu
   spariva/appariva male appena si scrollava (cioe' appena l'header
   riceveva la classe "scrolled" con il backdrop-filter). Con lo
   sfondo sul ::before, l'header resta "neutro" e il menu fisso
   funziona sempre rispetto allo schermo intero. */
