   设计规范（实测参考站 jianhu_shouye.css/jianhu_arc.css + 首页/详情/列表 HTML + CDP 截图）：
   - 主蓝 #2a7dc9（nav 通栏/按钮/标题）/ 深蓝 #1a6cb9（hover）/ 橙点缀 #ff6b00（签到/强调）
   - 页面底 #f5f5f5；白卡 + 4px 小圆角 + 轻阴影（0 1px 3px）；边线 #eee；文字 #333/#666/#999
   - 三段式头部：白色 topbar 细条 + 白底 header（logo+居中大搜索框+右侧绝对定位蓝钮）
     + 蓝色通栏 nav（hover 深蓝底 + 白色子栏目下拉面板）
   - 首页：hero 大图标语（底部黑渐变+白字）+ 5 快捷通道卡 + 两栏（最新资料 doc-list
     + 右栏热点分类 tag 胶囊云/本周热门）
   - 内页两栏：左列表/详情 + 右 sidebar（点击排行/最近更新/热点分类）
   - 详情：居中大标题 + 灰底 meta 框 + 蓝通栏「进入下载页」+ 资料简介/下载地址灰框
   - footer #333 深灰（免责声明 + Copyright + ICP）
   注意：pay-* 弹窗类名是 JS 契约不可改；JS 会 inline 设 display:block，
        弹窗内按钮必须自带 width + margin:auto 居中（勿依赖 text-align）
