+"""一次性 mock:造几条不同状态的用户反馈,供运营后台「反馈工单」页联调验收。
+
+覆盖:
+  - 三个状态 tab(待审核 pending / 已采纳 adopted / 未采纳 rejected),重点铺「待审核」;
+  - 两种反馈类型 source(普通反馈 profile /「我的」页入口、比价反馈 comparison / 比价结果页入口),
+    比价反馈带「问题场景」scene(找错商品/优惠不对/比价太慢…);
+  - 提交端环境快照(app_version / device_model / rom_name / android_version)——新端反馈才有,
+    另留 1~2 条历史反馈(env 全 NULL、contact 有值)测「旧数据」展示;
+  - 截图:在 data/media/feedback/ 生成真实可加载的纯色 PNG(手写字节,无需 Pillow),
+    让审核抽屉的图能真加载出来(与 seed_mock_price_reports 同法)。
+  - 已采纳条带 reward_coins + admin_reply + review_note;未采纳条带 reject_reason + admin_reply。
+
+幂等:每次运行先按固定 mock 手机号清掉旧 mock 用户/反馈 + 删 mock 截图再重建。仅清理用 --clean-only。
