   About / Technology / Platform / Support / Privacy / Terms 六页共用。
   首页 index.html 不引用本文件 —— 它是投放落地点，保持单文件零请求。

   🔴 下面的 :root 令牌是本文件与首页 index.html 的【唯一人工同步面】。
      首页那份在 index.html 的 <style> 开头（搜 "── tokens ──"）。
      改任何一边的配色都要同步另一边，否则首页与子页会分叉。
      （首页多一个 --rail，那是它左侧数据总线专有，子页没有该元素。）

   🔴 本文件被 nginx 按 `expires 30d, immutable` 缓存。改完内容必须跑
      deploy/stamp-css.sh 重刷六页引用上的 ?v= 串，否则老访客最长 30 天
      拿到旧样式，且没有任何报错。
