/*
 * Fortuna UI — kop van de site. Smal en rustig (64px desktop, 56px telefoon), vast bovenin.
 * Desktop (≥1024px): rubrieken in de balk; een rubriek met submenu opent een paneel over de volle breedte
 * met de sublinks en de nieuwste berichten (zoals Apple/Stripe). Telefoon: zoekknop + menu over het hele scherm.
 * Varianten: licht (standaard, wit met vervaging) en --groen (donkergroene balk). Gedrag: assets/js/site-header.js.
