   -----------------------------------------------------
   组织约定（页面样式拆分）：
   1. 本文件只放「整站统一」的公共样式，由 base.html 全局引入：
      设计变量 / Reset / 工具类 / 头部导航 / 按钮 / 通用栏目标题 /
      资讯列表组件（列表页与首页共用）/ 服务卡片组件（首页与服务
      总览页共用）/ 页脚 / 滚动动效 / 无障碍
   2. 各页面独有样式放在 css/pages/页面名.css（如 pages/index.css），
      由页面模板的 {block name="css"} 单独引入，不写在本文件；
   3. 完整设计稿保留在 html效果图/styles.css（权威母本），
      新页面需要的板块样式从母本拷贝到对应 pages/页面名.css。
