/* docs.qcode.cc 浏览体验样式
 *
 * 为什么不放 base.html 的内联 <style>：那段 CSS 每个 HTML 都要重传一遍（本来就有 20KB），
 * 而 HTML 响应没有 Cache-Control。放 static/ 走 VersionedStaticFiles 的 immutable 缓存，
 * 全站只下载一次。实测把这些规则内联会让文档页 gzip 后涨 16.3%，移出来后基本持平。
 *
 * 加载顺序：base.html 内联 <style>（含 :root 变量）→ theme.css（深色覆盖）→ 本文件。
 * 因此这里可以放心使用 var(--*)，也能覆盖前两者。
