/* ============================================================
   班级提醒时间表 —— 样式
   纯 CSS，无外部字体/图标依赖

   ★ 动效觉得刺眼或太安静，改这一小段就够了：
     · 卡片入场时长与幅度 → 搜 "@keyframes card-in" / ".card-anim"
     · 卡片淡化程度       → 搜 ".card--done { opacity"
     · 打勾动画           → 搜 "@keyframes check-pop"
     · 红点呼吸           → 搜 ".dot" / "@keyframes dot-pulse"
     · 悬浮按钮弹入       → 搜 "@keyframes fab-pop"
     · 卡片依次入场的节奏 → site/app.js 里的 WAVE_STEP / FLIP_MS
   ★ 系统开启"减少动态效果"时，下面会自动几乎不动。
