/**
 * Sidenav — mobile drawer.
 *
 * Intentionally empty. All sidenav styling lives as inline utilities on
 * the drawer markup in site-header.twig and on each menu item via the
 * `in-drawer:` custom variant (declared in src/theme.css). Kept loaded
 * via the `menutech_next/sidenav` library so the entry doesn't 404.
