   bootstrap-compat.css
   --------------------------------------------------------------------------
   项目只在自己 CSS 中手写了 Bootstrap 的一个子集（btn / form-control / modal /
   table / d-none …），但模板里还用了约 30 个「没写」的 Bootstrap 类，
   导致这些类静默失效（该加粗的不加粗、移动端表格不横滚、开关控件变形…）。

   本文件只做「补缺」：仅定义 app.css 中缺失的选择器，不覆盖任何已有规则。
   加载顺序必须位于 app.css 之后：
       app.css  →  bootstrap-compat.css  →  各页面 CSS(index.css / so.css …)

   同时补齐两个被引用但从未定义、导致阴影静默丢失的 CSS 变量：
       --shadow-soft（index.css .login-panel）
       --shadow-float（index.css .view-result-modal）
