/* =====================================================================
   全局样式表：数据看板（新项目）
   设计规则：
     - 全部列：左对齐
     - Tailwind CDN（index.html 引入） + 本地补充样式
     - KPI卡、表格、Modal、趋势浮层

   浏览器兼容性：
     - .filter-btn-toggle:has(input:checked) 需要 Chrome 105+ / Safari 15.4+ / Firefox 121+
     - backdrop-filter 已在所有位置添加 -webkit- 前缀兼容 Safari
     - clamp() / CSS Grid / Flexbox 为现代浏览器通用特性
