   手机适配(mobile.css)—— 覆盖 page-hud 的桌面断点
   ─────────────────────────────────────────────────────────────
   桌面 HUD(page-hud)在 ≤1180px 被 display:none 整个摘掉,
   手机上因此既没有顶边栏(logo/搜索)也没有任何导航 —— 这是
   "手机上导航有问题"的根源。这里的策略:
   1) ≤760px:恢复 page-hud 中的【顶边栏元素】(logo + 搜索 +
      右上角快捷按钮),用固定顶条布局呈现 —— 保留顶边栏设计;
   2) 桌面 HUD 的周边装饰(左侧竖条/右下番茄钟/ plants/投影)
      在手机上继续隐藏 —— 屏幕太小放不下;
   3) 导航交给悬浮按钮 + 圆盘面板(见 .mnav,交互在 js/mobile-nav.js)。
   仅在 ≤760px 生效,>760px 保持桌面体验原样。
