// apps/viewer/e2e/journey.spec.ts —— Task 11 跨端联调冒烟（Playwright 全流程，
// 真实后端 + 真实 MinIO/MySQL/Redis compose）。ONE 剧本串起三端：
//   ① admin UI（5176）：seeded admin 登录 → 建相册 A（zh+en）→ banner 真实
//      jpeg 走 file chooser（init→presign PUT→complete→预览，R09）→ 建分类
//      （zh+en）→ 账号前缀搜索邀 staffB → 登出；
//   ② staffB 经 API（UI 上传属 P3）：登录 → init×3（其一入分类）→ presign PUT
//      实写 → complete×3 → worker PublishService.processPhoto×3（services/api
//      full-chain 同款引导；BullMQ 队列消费路径由 api e2e 覆盖，此处直调 worker
//      发布事务）→ 公开列表恰 3 张（verify ready）；
//   ③ viewer UI（5175）：/a/{token} banner 渲染 → zh 信息 → 切 en 内容随切 →
//      瀑布流 3 张 → 分类 chip 过滤 1 张 → 大图开/缩放/关 → 深链直达；
//   ④ admin UI 再登录：照片管理 3 行（就绪/已发布）→ 隐藏 1 张 → viewer 重载
//      剩 2 张 → 被隐深链 404 本地化提示；
//   ⑤ 空相册 B（admin API 建，无照片）：viewer 空态提示「照片即将上线」。
// P2 Task 6 起 viewer 观众腿读 ov 副本（VITE_API_BASE 直连 8081）——本剧本的
// cn 侧变更（发布/隐藏/建 B 相册）在各 viewer 腿前 flushSync（bootstrap 快照 +
// 真实发送管线排空）投影到 ov；admin/staffB 腿仍走 cn 8080（代理/直连，不变）。
// 数据清理：afterAll 按 viewer helpers 同序直删（含 album_members/upload_sessions/
// photo_jobs/outbox_events 等 API 链路落库行）+ staffB 账号域行。
