/* ===========================================================================
 * GeoTrack 自托管字体 (self-hosted fonts)
 *
 * 为什么自托管: Google Fonts (fonts.gstatic.com / fonts.googleapis.com) 在国内
 * 被墙, 会导致首屏字体加载失败 → 全站回退 system-ui。改为把 woff2 放进
 * public/fonts/, 线上经本站同源 /fonts/*.woff2 提供, 不依赖任何外部 CDN。
 *
 * 字体来源: @fontsource 预构建 woff2 (jsDelivr CDN 下载, 与 Google Fonts 同源数据)。
 * 覆盖 v52-tokens.ts FONTS 用到的全部族名与字重:
 *   - Sora           400 / 500 / 600 / 700   (display 标题)
 *   - Outfit         300 / 400 / 500 / 600   (body 正文)
 *   - JetBrains Mono 400 / 500 / 600         (mono 数字/等宽)
 *   - Noto Sans SC   400 / 500 / 600 / 700   (中文兜底; chinese-simplified 子集)
 *
 * 族名 (font-family) 与 v52-tokens.ts 完全一致, 故令牌无需改动 —— 此处提供同名
 * @font-face 即可让全站生效。font-display:swap 避免 FOIT(不可见文字闪烁)。
