// Everything structured lives here — never inside a chat bubble.
// Layout only: data, actions and sub-sections are unchanged,
// just grouped into cards instead of one <br>-separated block:
//   概览（状态 + 耗时/token/成本三张指标卡）
//   基本信息（键值网格）
//   prompt（单独一张卡，长 prompt 不再挤在信息行末尾）
//   操作与结果
//   协调子任务 / 子代理链路 / 评审队列 / 运行时审批队列 /
//   给其他任务发消息 / 线程（各一张卡）
