- 加入资产库入口删错对调:恢复单图「更多」入口(单图粒度入库),
  删掉整批底部气泡里与独立按钮重复的入口(cover/model/对话流)
- 新建商品抽屉补显式「添加卖点」按钮(原仅回车确认太隐晦)
- 平台套图筛选生效 → 结果区顶部「已开启筛选」提示栏,点清空退出
- 去掉结果批次卡白色容器/边框/内边距+底部分割线,图片区更大
- 未读生成任务角标:AITask 加 read_at 字段(迁移 0020)+ unread/
  mark-read 接口;导航「图片生成」数字胶囊 + 工作台商品缩图右下未读分数;
  30s 轮询,进任务中心全清、工作台看哪个商品清哪个

注:同区文件含上一轮未提交的 PMC#25 重跑/追加批次逻辑,一并带入。
