/*
模块名称：代理池界面样式（pool.css）
功能描述：代理池页签的池启停条、概览统计卡、区块与工具条、提示条、批量任务进度、插件表、
          代理列表（筛选 / 批量操作 / 表格 / 分页 / 徽标）与导入导出弹窗。
职责边界：负责：以代理池页签为主，兼含访问记录页与全局组件复用的通用类（.filter-bar、.pager、
          .icon-btn、.modal-box-wide、.tbl-clean 空态）；不负责：设计变量与 .btn / .fg-* /
          .tbl-clean / .modal-* 基础组件（由 main.css 负责）。
关键依赖：main.css 的设计变量与基础组件；index.html 静态模板提供池页骨架 DOM 与类名，并保证本文件
          在 main.css 之后加载；pool.js / proxies.js 渲染动态行；body 状态类 batch-bar-open、
          col-resizing 仅由 proxies.js 切换；.icon-btn 另用于全局移动端顶栏、行抽屉与 app.js 用户表。
已知限制：
  1. 768px 断点必须留在本文件：本文件后加载可覆盖 main.css 同特异性规则，搬进 main.css 即失效。
  2. .chk-inline:not(.switch) 的 :not 必需：两者特异性相同，去掉会把插件表开关压成方框。
  3. .cell-clip 的截断必须落在行内 span 上：自动布局表格会忽略 td 自身的 max-width。
  4. 批量操作条是 fixed 浮层：sticky 会被祖先裁切；body.batch-bar-open 由 proxies.js 切换用于让位。
  5. z-index 阶梯：列宽拖拽手柄 3 < 批量操作条 40 < 回到顶部按钮 900。
  6. 概览卡着色落在内层 .stat-val；未验证与兜底徽标用中性色、虚线边框，勿与实测档同色。
