/* Nixo Mega Menu — touch / focus support.
 *
 * The default reveal is hover-based via `group-hover/li:` (Tailwind v4
 * variant). On touch devices and for keyboard users, we need a JS-driven
 * fallback. The walker adds the class `nixo-megamenu-item` to the parent
 * <li> when the mega menu is enabled; Alpine toggles the
 * `nixo-megamenu-open` class to force-show the dropdown.
