/*
 * OMTRA mega menu - full-height cascading columns, any depth.
 * Design: Figma "OmtrAdvisory", nodes 4101:66 / 4101:119 / 4101:176. Colours and fonts from the site.
 *
 * Every selector starts with #main-menu .om-mm: the theme dropdown rules on .header__menu,
 * .header__menu--dropdown/--hoverable and li.current-menu-ancestor must not reach the columns.
 * Panels are hidden below the theme breakpoint because the theme hides the top items there.
