/* ============================================================================
 * 班级日常（老师端「班级日常」模块 + 学生端「课堂记录」）专用样式
 *
 * 为什么单开一份：这一块有自己的一套小部件（课次行、到勤按钮组、图片墙、
 * 视频卡、拍照取景框），塞进 app.css 会把那份已经很大的文件继续撑大。
 * 所有类名统一加 dl- 前缀，避免和 app.css / text.css / show.css / meet.css 撞车。
 * 基础件（.card / .card-head / .btn / .tag / .empty / .loading）继续复用 app.css。
