   · Mobile (≤768px): hamburger fisso in alto a dx → overlay liquid glass
   · Desktop: nessun header in cima (hero pulita); barra glass #nkBar
     scende quando scrolli oltre 160px e resta finché non torni in cima
   · Gli header legacy per-pagina (.nk-nav, #nk-hnav) vengono nascosti:
     la navigazione è SOLO questa componente, iniettata da nk-header.js
