/* ---------- 字体：自托管优先 + 双 CDN 兜底 ----------
   Inter      : 拉丁 + 西里尔（英文/俄文）
   Vazirmatn  : 波斯文（伊朗本地设计，Google Fonts 在伊朗被广泛屏蔽，自托管是唯一可靠方案）
   中文        : 系统字体栈，不下载 web font（中文字库过大，且国内系统字体已足够好）

   实测结论（2026-10-02，勿轻易改动 src 顺序）：
   - registry.npmmirror.com 是 npm 私有 registry，只同步 tarball，
     不提供 /files/*.woff2 这类扁平文件访问 —— 实测全部 404，不可作为字体 CDN
   - staticfile / bootcdn / 百度字体库 均不托管 fontsource 字体
   - cdn.jsdelivr.net 稳定可用（含国内访问），作为兜底源有效

   因此采用三层策略：自托管（本站，最可靠）→ jsdelivr → 系统字体栈。
   自托管总开销 113KB（latin 48KB + cyrillic 18KB + arabic 46KB），
   按 unicode-range 分片，只有真正用到该字符集的页面才会下载对应分片。
