   实验室管理系统 · 统一界面样式库 (lab-ui.css)  v1.0
   -------------------------------------------------------------------------
   所有模块必须引用本文件，并遵循以下约定：
   1. 颜色 / 圆角 / 阴影一律使用 CSS 变量（见 :root），禁止硬编码；
   2. 组件类名统一使用 lm- 前缀（lm-header / lm-btn / lm-table …）；
   3. 模块页面结构：lmHeader + lmNav + lmMain + lmFooter，导航由 lab-shell.js 渲染；
   4. 图标统一使用 Emoji，不引入图标库。
