/**
 * 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.

/* ── Scroll behaviour — sticky / sticky-shrink / hide-on-scroll / transparent-to-solid ──
 *
 * State model (set by bps-menu.js's scroll handler, additive to the base model above):
 *   .bps-menu--has-scroll-behaviour   sticky_mode !== 'none' (any of the 3 non-default modes)
 *   .is-stuck                         scrollY has passed the instance's shrink_threshold
 *   .bps-menu--transparent            transparent_start = true, present at initial paint
 *   .bps-menu--transparent-solid      added once .is-stuck (transparent -> solid transition)
 *   .is-hidden                        hide-on-scroll mode, scrolling down past threshold
 *
 * 🔴 `position: fixed` (on .is-stuck), NOT `position: sticky` — deliberate, and do not
 * "simplify" it back. BPS ships a global `body { overflow-x: clip }` (assets/scss/
 * bps-framework.scss:1008, the BUG-234 fix). That comment correctly notes clip does not
 * create a SCROLL container — but any non-`visible` overflow on <body> still makes it the
 * containing block for sticky descendants, and <body> itself never scrolls (the document
 * does), so `position: sticky` moves 1:1 with the page and never pins. Measured on the
 * sandbox: computed position was `sticky`, top `0px`, no interfering ancestor — and
 * getBoundingClientRect().top after a 500px scroll was exactly original−500, i.e. zero
 * pinning. The estate's own .bps-sticky-header (bps-framework.scss:41-59) uses
 * position:fixed for exactly this reason; this follows that proven precedent, including its
 * admin-bar offset.
 *
 * Because fixed removes the nav from flow, bps-menu.js inserts a same-height spacer <div>
 * so content below does not jump when the nav sticks.
 *
 * Colour/shadow/height are themeable via --bps-menu-* (rung-3/4 override seam, CSS
 * escalation ladder) rather than hardcoded. Applies to the .bps-menu element itself — this
 * widget controls its own <nav>, not a wrapping header container, so a "sticky whole header"
 * composition (logo + CTA alongside nav_menu) needs the site's header container built around
 * this widget. Out of scope for the widget itself.
