   自托管字体（同源自托管，规避国内访问 Google Fonts 被墙/超时）
   ------------------------------------------------------------
   Chakra Petch 600/700  → 展示字：标题、数字、导航（工业/仪表盘气质）
   IBM Plex Sans  可变    → 正文字：克制、内敛、与展示字形成对比
   JetBrains Mono 可变    → 等宽：版本号、统计数字、终端面板
   Inter（旧）            → 仅 admin.css / memo.css 仍在用，保留避免后台排版回退
   全部只取 latin 子集，中文回退到系统字体栈（PingFang / 微软雅黑）。
