/**
 * File: bps-menu.css
 * Path: assets/themer/bps-menu.css
 * Version: 1.0.0
 * Last Modified: 2026-07-28
 *
 * Front-end behaviour styles for the BPS nav_menu Themer widget
 * (BPS_Themer_Widget_Renderers::nav_menu). First front-end stylesheet in the
 * widget system — deliberately structural: layout, dropdown/mega/overlay
 * mechanics, collapse states. Colours/spacing inherit from the site unless a
 * --bps-menu-* custom property overrides them.
 *
 * State model (set by bps-menu.js):
 *   .bps-menu--collapsed  below the instance breakpoint (or always, overlay)
 *   .is-open              on the nav  = toggle panel open
 *   .is-open              on an item  = submenu expanded (accordion/touch)
 * No-JS fallback: no collapse class ever applies, so the menu renders
 * expanded with hover/focus-within dropdowns — fully usable.
