/*
 * 品牌字体,自己托管(第 8 阶段 Lighthouse 检查,产品负责人 2026-10-19 定)。取代原来的 Google Fonts 样式表:
 *
 * - 隐私:从 fonts.googleapis.com 加载时每次打开页面都把访客 IP 发给 Google,而隐私政策里没写这个第三方
 *   (欧盟有判例认定这违反 GDPR);同源发就没有这回事。
 * - 速度:Google 的样式表挡首帧,字体又是另一个域名;快照先用系统字体画、网页字体后到,
 *   真页面接手时文字略大,Lighthouse 记成一个更晚的 LCP(G4 指南 6.6 s)。同源 + 预加载让字体赶上首帧。
 *
 * 文件是 2026-10-19 从 Google Fonts 下的可变字体(与原来那条 link 同参数:Bricolage Grotesque 的 opsz 轴 +
 * 500–800、Instrument Sans 400–700、JetBrains Mono 400–500),每款只留 latin 与 latin-ext 两个子集
 * (正文都是英文;中文界面本来就落到系统字体)。字重范围、unicode-range 照 Google 当时给的样式表抄,
 * 换字体要连同 OFL.txt 一起换。字族名与 `tailwind.css` 的 `--font-display / --font-body / --font-mono` 对得上。
 *
 * 放在 public 里由页面直接 link,不进 tailwind.css:打包器不碰这里的 url(),dev 与 build 同一份。
 * 预加载的两份(Instrument Sans、Bricolage Grotesque 的 latin)写在 `config/config.ts` 的 `links`。
