   汉魏优选 · 全站布局视觉系统（顶部导航 + 底部 + 悬浮客服）
   --------------------------------------------------------------------------
   针对老站问题的改进：
   1. 品牌统一 —— 老站头部 #3498db 亮蓝 / 底部 #1a2332，与业务页 #1e40af 靛蓝
      割裂；本文件沿用 business.css 的 CSS 变量，全站一个视觉语言。
   2. 信息层级 —— 新增顶部工具条（电话 / 地址 / 服务时间），让客户第一眼
      看到联系方式，而不是埋在页面里。
   3. 导航体验 —— sticky 吸顶 + 滚动阴影 + 下拉面板 + 当前页高亮 +
      移动端抽屉菜单（老站移动端只能横向溢出滚动）。
   4. 合规完整 —— 底部补齐 ICP 备案、公安备案（含官方图标）、增值电信业务
      经营许可证，老站虽有但散落在硬编码 HTML 里，此处集中到 config/site.php。
   5. 转化入口 —— 底部保留在线客服悬浮（电话 / QQ / 微信二维码）。
