 *  app.orangray.top/pan/  ←  nginx sub_filter 注入
 *
 *  设计语言：CRT / JR East 信息导视（与 orangray.top/design-system 同构）
 *  主色：CRT 19 号线「远黛蓝」PT2935C #0047BB（OO 的年龄线）
 *  辅色：环线柠檬黄 PT130C #F5C400（仍在关联的人）
 *
 *  ⚠️ OpenList v4 前端 = SolidJS + Hope UI（stitches 运行时注入）。
 *     运行时样式带 hash 类名且后于本文件加载，所以这里只做：
 *     1) CSS 自定义属性层面的 token 覆盖（!important 兜底）
 *     2) 结构性、外观性覆盖（背景、圆角、字体、滚动条、选中色）
 *     3) 精准选择器留给 pan-theme.js 在 DOM 挂载后补刀
