• 参考 PixVerse world.pixverse.video/live/dress 的交互设计(分析见
    docs/reference/pixverse-dress-live/NOTES.md),按 docs/todo/dev-plan-6.md
    的任务表实现:
    
    - T40: 顶部"正在换装"胶囊 + 排队头像条
    - T41: 换装卡片 hover/点击展开"发送"态,避免误触直接提交
    - T42: 右侧"选衣服"网格改为贴视频底部的横条,"传衣服/传人"付费上传
      入口合并进横条末尾的 DIY 卡片二选一弹窗,左栏撤掉多余 tab
    - T43: 修复移动端视频宽度驱动的 9:16 布局把"待播放"挤压到不可用的
      问题,改回高度驱动
    - T44: 上传进度条(伪进度+真实 XHR 进度混合)
    - T46: dance room 专属聊天(不复用 /api/chat 以免误触发生成任务,
      独立限流/审核/按房间隔离存储)
    - T48: 同一访客同时只能有一条免费换装请求在排队,付费上传不受影响
    
    新增/修改的后端集成测试覆盖 T46/T48 的核心行为;node --test *.test.js
    142/142 通过。

  • Same shape as T28's 传衣服 panel: file input, live price pulled from
    GET /api/pricing (今 spend_character_per_segment × segmentsPerUnit,
    not hardcoded), a garment picker (随机搭配 default, or any wardrobe
    item, 需求文档 3.3 第 4 点), a segments-to-buy input (1-20, matches the
    server-side clamp), not-logged-in opens the existing login modal
    instead of failing silently, insufficient balance points at the topup
    flow. Success message is visually distinct ("boosted", yellow box,
    🎉 已插队播放") from mode 1/2's plain "生成中" — T37's explicit
    acceptance criterion that a paid_boost submission must be recognizable
    as skipping the vote queue, not just another queue entry.
    
    Also fixes a real bug this surfaced via a live smoke test (not just
    new to T37 — T28's submitGarmentUpload had the identical bug): both
    upload handlers set the success/status message and *then* called
    `await refreshAuthState()`, which re-renders the whole panel
    (creditBalance changed -> renderAuthButton -> renderWardrobe) and wipes
    whatever was just set. Both now set the message after refreshAuthState()
    resolves, re-querying the fresh DOM it produced.
    
    Seeded the live pricing.json with spend_character_per_segment (it only
    existed in pricing.js's DEFAULTS, which don't retroactively apply to
    an already-existing file — the same class of gap as the isDefault
    character fix two commits ago).

  • T28 replaces the "开发中敬请期待" placeholder on dance.html's 传衣服
    tab with a real upload panel: file input, the live spend_garment price
    pulled from the new public GET /api/pricing (not hardcoded, per
    dev-plan-4.md's acceptance criterion), and a submit flow that POSTs to
    T27's /api/dance/upload-garment. Not logged in opens the existing T22
    login modal instead of failing silently; not email-verified shows an
    inline message; a 402 (insufficient balance) points at the new topup
    flow; success refreshes the balance and immediately polls the queue,
    same as the free wardrobe pick's own pollState() call.
    
    T29 adds a 充值 pill (visible once logged in) opening a tier picker
    built from GET /api/pricing's topup_tier entries, POSTing to T24's
    /api/credits/checkout and navigating to whatever URL comes back (the
    mock completion page today, Stripe's hosted Checkout once a real key
    lands tomorrow — both redirect back to dance.html?topup=success/
    cancelled). A one-shot banner reads that query param on load, then
    scrubs it via history.replaceState. The account button's own label
    now also shows creditBalance, riding on the field GET /api/auth/me
    already started returning in T24.
    
    Manually verified end to end against the live server (localhost:8934):
    register -> verify -> mock checkout -> balance updates in the header
    -> topup banner -> upload panel shows the live price and opens the
    login modal when logged out. The upload itself surfaced that
    production's one seed character had never been marked isDefault (see
    the preceding commit) — not a bug in this code, but blocked a live
    walk of the full generate path until fixed.

  • Backend (server.js):
    - T11: dance.html gets its own schedule/queue state machine, persisted to
      dance-state.json (gitignored, same as live-state.json). Per MVCP M.8,
      the schedule stores videoId references rather than inlined clip
      snapshots like live's does, joining back to library.json at read time.
      Generalized pickBestIndexByStatus/extracted pickLeastPlayedClip so both
      channels' schedulers share the same selection logic instead of forking
      it; live's random-fill pool now excludes channel:"dance" clips (and
      vice versa) so the two channels' filler picks stay independent, which
      wasn't true before this (T8's dance clips could have leaked into
      live.html's filler).
    - T12: GET /api/dance/wardrobe — public, unauthenticated list of active
      garments.
    - T15: POST /api/dance/pick {garmentId, nickname?} — free path, always
      uses the configured default character, reuses submitGeneration (T8/T9)
      whole including its M.7 dedupe cache, then hands the result to
      danceQueue. In-flight generations are reconciled against generationJobs
      on each schedule tick rather than via a promise chain, so a pick
      request survives a server restart the same way T8's own jobs do.
    - T17: separate danceViewers map and POST /api/dance/queue/vote/:id, so
      viewer counts and votes don't mix with live.html's.
    - SCHEDULE_TICK_MS env var makes both channels' tick interval
      configurable so tests don't wait out a real 2s.
    
    Frontend:
    - dance.html (T13/T14/T16): reuses live.html's visual language via
      live.css, adds dance.css for the 9:16 boxed player and wardrobe grid.
      Left column is a 衣柜/传衣服/传人 tab set (only 衣柜 is wired up —
      the other two need accounts/credits, dev-plan-2.md 第三/四期); right
      column shows the queue with vote buttons instead of live.html's chat.
      Age-confirmation gate (5.1节) blocks the page on first visit via a
      cookie, non-dismissable by clicking the backdrop.
    
    Tests: dance-channel.test.js spins up a mock H3 Console (same approach
    as dressup-generate.test.js) to exercise wardrobe listing, pick
    rejection/happy-path/dedupe, vote, and independent viewer counts
    end to end.
