   自托管字体（无任何外部字体域名请求）

   Inter / JetBrains Mono：latin 静态子集，承担西文、数字与等宽标签。
   Noto Sans SC：按本站实际用字（983 个非 ASCII 字符）切块子集化的
     **可变字重**字体，一个文件覆盖 100-900 全部字重，无需为每个字重单独下载。

   为什么不用 Google Fonts：
   fonts.googleapis.com 与 fonts.gstatic.com 在中国大陆不可达。原先用
   <link rel="stylesheet"> 引入时，浏览器会因等待该请求超时而阻塞渲染，
   国内面试官打开页面会看到长时间白屏。

   每个 Noto 分块都带精确的 unicode-range，浏览器只会下载当前页面真正
   用到的那几块；若日后新增了子集之外的汉字，会平稳回落到系统中文字体。
