 * 1) 只由 source/site/census/index.md 通过 <link> 引入，其它页面不加载；
 *    原来那大段写死在 markdown 里的 <style> 已挪到这里（顺带解决它被 Hexo
 *    当成页面摘要写进 <meta name="description"> 的问题）。
 * 2) 配色全部从主题色 --theme-color 派生，深色模式只覆盖变量、规则本体一套；
 *    每个自定义属性第一行是「不支持 color-mix() 的老浏览器」的回退值。
 * 3) 回滚：删除本文件并还原 bak/20261004-census-redesign/ 下的两个备份即可。
