/* =========================================================================
 * Header categories (RU · knigaotebe) — mega menu (≥1025px) + drawer (≤1024px)
 * -------------------------------------------------------------------------
 * The mega-menu nav replaces the content of the Elementor nav-menu widget in
 * the two header templates (13317 / 13320); the widget keeps its own
 * `elementor-hidden-tablet elementor-hidden-mobile`, so ≤1024px only ever
 * sees the burger, which now opens `#fbnav-drawer` (printed in wp_footer).
 *
 * Panels are moved by nav-ru.js into `.fbnav-megas`, a child of the
 * <header>, so they can span the full page width and sit under the header row.
 * ====================================================================== */
