/* ==========================================================================
   工程部质量中心知识库 · 全站移动端适配层   mobile.css   (v2.0 重写版)
   --------------------------------------------------------------------------
   加载方式：由所有页面在 widescreen.css 之后引入，因此同权重声明以本文件为准。
   覆盖的页面体系（四套并存）：
     1) 首页 / 门户页      —— index.html、digital-twin/index.html
     2) 实验室管理页        —— laboratory 体系   （lab-common.css）
     3) 培训 / 试题页       —— training/tests 体系（test-common.css）
     4) LIMS 数据看板       —— lims/lims.html（页内样式）
   重写要点（v2.0 相对 v1.0 的改动）：
     · 删除 v1.0 的「大锤」规则：[class*="grid"]、[class*="card"]、[class*="icon-"]
       等通配选择器会误伤大量无关元素，并把所有卡片压成全宽单列；已全部改为
       针对真实类名的精确规则。
     · 删除 `div/span/p/li` 等 `font-size: inherit !important`：它会把全站字号
       压平到 13px，摧毁原有层级；改为只压缩「过大的展示型字号」。
     · 修正 v1.0 用 body 承载安全区导致实验室页 24px 内边距被清零的问题，
       安全区改由 html 承担。
     · 补齐「标签/徽章」统一宽度规则（v1.0 缺失）。
     · 修复 widescreen.css 把 .table-box 设为 overflow:hidden 造成表格撑破
       页面的问题。
   分级：基础规则全尺寸生效且安全；布局/字号变化只在窄屏与原生 App 生效。
