/* ==========================================================================
 * 商户后台 · 顶部壳层增强（zhc-shell）
 * 1) 深色通栏：只在 .admin-topbar 作用域覆盖 CSS 变量 —— 侧栏/内容区不受影响
 * 2) 汉堡按钮 + 高频待办标签（数字来自真实接口）
 * 3) 「全部应用」抽屉（内容从侧栏菜单实时抓取，不维护第二份菜单数据）
 * 4) 右下角悬浮：帮助 / 客服 / AI 中心 / 回到顶部
 * ★ 所有类名带 zhc- 前缀：宿主有通用类（.primary/.danger 等），不加前缀会被吞
