/* ============================================================
   觅水狸 · 前台样式

   布局、栅格、按钮、表单、徽章、模态、响应式断点全部交给 Bootstrap 5，
   这里只放三样东西：
     1) 品牌色变量
     2) 对 Bootstrap 组件的品牌化覆盖（改的是 --bs-* 变量，不写 !important 硬覆盖）
     3) Bootstrap 里没有的组件：城市搜索弹层、招商占位卡、招商带、Toast

   Bootstrap 文件位置：public/vendor/bootstrap/（本地，不依赖外网 CDN）
