   ⚠️ 2026-09-20：网页版学生端（read/login/history）已下线，本文件现存两重身份：
     ① 老师后台 /admin.html 的样式表（唯一线上消费者）；
     ② .selfcheck/mp-parity.js 的 H5 侧样式基准 —— 标注「read.html 专用」的段落
        仍参与契约比对，**不要当死代码删掉**（删了门禁会红）。
   ⚠️ 2026-10-05 全量引用链核对（.selfcheck/css-ref-chain.js）：还有第三重身份——
     ③ .frozen-h5/ 冻结存档（read/history/login，勿改勿删）仍直接 <link> 本文件。
     275 个类中约 186 个在现役两页（admin/index）零引用，但绝大多数被冻结存档或
     mp-parity 契约使用；**真正全项目零引用的只有约 18 个**（admin-tbl、ti-icon、
     user-badge 等），删除收益几 KB、误删风险是冻结页裸奔 → 结论：本文件不做
     「死样式清理」，未来要动必须先跑 css-ref-chain.js 核对引用链。
