/* ============================================================================
   移动/触屏布局（<=1000px）：按「手机优先」重新设计，而非压缩桌面版
   设计目标
   1. 拇指可达：主要操作落在下方 1/3 屏幕
   2. 不靠 hover：全部交互在触摸下明确可用
   3. 内容优先：去掉桌面端为横屏构图服务的装饰层

   为什么上限是 1000px 而不是 760px：
   上游 1000px 断点已经隐藏了桌面导航（.nav{display:none}）。
   若这套布局只写到 760px，那么 761-1000px 就会落进空档 ——
   桌面导航没了、手机汉堡按钮还没出现，用户完全没有区块跳转入口；
   同时装饰遮罩仍在吃触摸、弹窗仍开 blur。
   iPad 竖屏(768)、很多安卓平板(800/962)、小笔记本窗口都在这个区间，
   所以这里必须一路接到 js 里 desktopQuery 的 (min-width:1001px) 为止。
