/*
- 开发时间：2026-07-03
- 更新时间：2026-07-06
- 文件作用：cloudPrompt「1点01」任务管理页面专属样式
- 实现原理：列表视图（工具栏 + 状态 tab + 任务卡片含执行中进度圆圈）和详情视图（6 段）样式；
            任务卡片左侧色条按优先级标识（high红#dc3545 / medium黄#f57c00 / low蓝#1976d2）；
            已完成任务卡片置灰 + 标题划线；
            详情页子任务：按 seq 整数分组收拢/展开（带标题+全部完成自动收拢）、seq 徽章双击重命名（max 10 字符）；
            详情页标题双击重命名；新增子任务栏置于顶部含序号输入
- 如何调用：由 tasks.html 通过 <link rel="stylesheet" href="tasks.css"> 引入
- 所属流程：cloudPrompt 任务管理流程（1点01）
