   全天电脑维修 · 全站共享导航样式（唯一真源）
   --------------------------------------------------------------------------
   适用：SSR 页面（app/web/view/layout/base.html）与 9 个独立静态页
        /tools/ 7 页、/speedtest/ 2 页。
   规则与 public/static/web/site.css 中的导航段保持一致，另加「当前页高亮」。
   所有值均为硬编码色值，不依赖 :root 变量，避免被静态页自身的 CSS 变量覆盖。
   加载顺序：必须放在各页自有样式表之后。
