Both are pluggable seams (dev-plan-4.md §1.2 items 1-2), same shape as
T20's sendVerificationEmail: a fixed env var gates a real vendor call
that isn't implemented yet (none has been picked), and the no-vendor
path is what actually runs today.

describeGarmentImage() — mode 2 has no admin around to hand-write
garments.appearanceDescriptor the way admin_seed garments do, so it
needs *something* non-empty to fill that field; today that's a fixed
placeholder string, swapped for a real vision-model call once a
vendor's picked.

moderateGarmentImage() — the requirements doc flags image-content
moderation as vendor-TBD but never actually lists it as its own task;
this fills that gap. Every call writes a moderation_log row (new
dressup-store.js export, M.9 schema) regardless of which branch runs,
so the audit trail exists before a real vendor does. Default-permissive
when unconfigured — T2's upload endpoint already enforces the real
trust-boundary checks (magic-byte type check, 8MB cap, EXIF-stripped
re-encode); this only covers the *content* check, which nothing here
can perform without a vendor.

Neither is unit-tested standalone (server.js doesn't export internal
functions, matching sendVerificationEmail's existing precedent) — T27
integration-tests both through the actual upload endpoint.

Also adds pricing.js to the tmpdir file-copy list in every test that
spawns server.js in isolation — server.js now requires it.

POST /api/auth/register, POST /api/auth/login, POST /api/auth/logout,
and a debug GET /api/auth/me (T19's own acceptance criteria calls for
it explicitly). Passwords hashed with node:crypto's scryptSync (salt
stored alongside the hash, verified with timingSafeEqual) — still zero
new dependencies.

Sessions live in a separate user_session cookie from admin_session
(T6) — the two are unrelated systems, confirmed by a test that a user
session can't unlock /api/admin/*. Login and "email not registered"
return the identical 401 body so the endpoint can't be used to
enumerate registered emails.

Every test file that spawns server.js in an isolated tmpdir now also
copies db.js alongside it (dance-channel/dressup-generate/dressup-crud/
admin-pages-flow/uploads-route .test.js) — server.js requires db.js
unconditionally now, so those child processes were crashing silently
without it.

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.
