   Zibll hardcodes body.nav-fixed { padding-top: 88px } + position: fixed on
   .header, but when menu items wrap the header grows beyond 88px and overlaps
   content. Switching to sticky keeps the header in document flow so content
   naturally sits below it regardless of header height.
   :has() for instant CSS, .nude2-sticky-nav JS fallback for older browsers. */
