/* ==========================================================================
   FFW Theme — Fahrzeuge Mega Menu
   ========================================================================== */

/*
 * How it works
 * ------------
 * Any primary-nav top-level item that carries the WordPress CSS class
 * "mega-menu" (set in the menu editor) also receives "has-mega-menu" from
 * the custom Walker.  Its children are rendered as .mega-menu-card divs
 * inside a .mega-menu-panel wrapper instead of a plain <ul>.
 *
 * The panel is positioned absolute relative to .site-header (position:sticky)
 * because the <li> itself has position:static, which skips it as an
 * offsetParent — the next positioned ancestor is the sticky header.
