- admin-dance-library.html: 高清重绘 tier 列（HD_RENDER_TIERS 与 server.js
  保持一致），HD 变体内联在根 clip 行而不单独占行；有 hd_render 在飞时
  每 20s 自动轮询刷新；新增高清状态筛选
- dance-rooms.html: 房间网格 3 列 → 4 列，去掉 max-width 让大屏真正铺满，
  卡片改 aspect-ratio 4/5 等比缩放替代固定像素高度
- H3-CONSOLE.md: 补 POST /v1/videos/{id}/cancel —— 真正取消排队/运行中的
  任务并释放算力，DELETE 只是从列表隐藏（2026-09-09 实测）
- blacklist.json 首次纳入版本管理（同级的 garments/dance-refs 一直是
  tracked，这个之前漏了）
- dance-refs/garments/generation-jobs.json: 素材库与任务流水数据更新

Extends the 跳舞直播间 (dance room) system to one independent live room
per character, with an operator playback-management/blacklist layer
(T39), a "我的作品" page for paid users (T38), a standalone 人衣图生成
admin tool, and a new admin-dance-library.html page for curating the
per-character dance clip pool with AI QC.

On top of that, dance clips now have an explicit published (上架/下架)
status: passing AI QC (or a manual admin override to "correct") auto-
publishes a clip, failing it auto-unpublishes it, and only published
clips are eligible for a room's random-fill pool — unreviewed/rejected
clips stay in the library but no longer autoplay for viewers. Existing
already-QC'd "correct" clips are backfilled to published on first boot
so the room doesn't go quiet.
