 *
 * Zustände (setzt wab-header.js auf .wab-site-header):

 *   is-fixed      Leiste ist fixiert, .wab-site-header hält den Platz frei
 *   is-topbar-hidden  Seite ist gescrollt (ab 1 px) → Topbar weg
 *   is-scrolled   Scrollstrecke über „Verkleinern ab (px)“ → Header niedriger
 *   is-compact    Navigation passt nicht in eine Zeile → Burger-Menü
 *   is-open       Burger-Menü ist geöffnet
