Conversation
Short ads and brand films have no narration, so their clock is the music:
promo/promo.json sets bpm, key and per-scene bars/energy/transition/cues
("bar:beat"); scenes read frames with usePromo(); tools/score.py writes the
score on the same grid. A 15 s 9:16 demo (7 scenes, 128 bpm) promotes the kit.
- core: land()/squash() so hits arrive on their frame, <Burst> ballistic
particles, shared font loading, SfxMute for frozen transition copies
- punch pack: Slam (RGB split), Hud, Marquee, Badge, CardStrip with motion
blur, PatternText, Wipe, LogoReveal, CtaBar; works as a Look too
- sound: synth.py instruments + energy-normalized reverb + sidechain;
master.py measures, applies linear gain and a look-ahead limiter, and checks
true peak on the AAC-encoded file; mix.py now masters to loudness.target
(-16, 9x16 -14); audio-report.py prints per-section loudness and draws
waveform/spectrogram; five new sfx (impact, riser, revcrash, shimmer, rush)
- tools: trace-logo.py (logo image -> vector parts), copy_lint.py (absolute
claims barred by China's Advertising Law), promo.mjs, promo-sheet.mjs
- verify: two promo stages (every cue renders; determinism)
- fix: WAVs written by Python's wave module (minimal header) crash Remotion
4.0.532 renders on Windows with "kill EBADF"; every scene WAV is now written
with a LIST/INFO chunk via wav_bytes(), enforced by a test
- fix: demo s08 coin/levelup sfx were ~3.5 LU hotter than neighbouring scenes
- docs: principle 1 generalized to "one time source: the sound", principle 7
"measure the sound to delivery spec"; README, CLAUDE.md, new-promo skill

- src/core/probe.tsx: measures every readable text box on the rendered frame (transforms, masks, opacity included) against promo.json "safe" (status bar, caption line, button rail); <Free> / data-copy="free" for decoration - verify stage 5 and promo-sheet probe frame 0 (must carry copy), every cue once settled, transition midpoints and the cover; failures outlined in red - promo.mjs runs the safe-area check before rendering and exports out/<id>-cover.png from promo.json "cover" - relayout p1-p7 so all copy is inside the safe area; the first slam lands on frame 0 - pack counts on screen derive from PACKS (now all 10 packs); tests check PACKS against the packs on disk and reject hard-coded counts - principle 8 in docs/principles.md; new-promo/review skills, README Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Hf6CivwFE1rx9Hf8pbNvaS

内容
这个 PR 包含两个提交：
1.
7b0eaed短片模式、punch 风格包、交付级声音（来自iterate-punch分支）promo/promo.json+src/promo/：没有旁白的 15 秒竖屏短片，cue 写成「小节:拍」，转场在重拍上收住punch风格包：Slam 砸字、HUD、跑马灯、徽章、卡片轮播、图案填充字、LogoReveal、CTA 条；<Burst>粒子score.py/synth.py按同一网格写配乐，master.py母带到 -14 LUFS，audio-report.py分段响度报告；copy_lint.py（广告法绝对化用语）；trace-logo.py；WAV 写入 LIST/INFO 块，修复 Windows 上的kill EBADF2.
e5bbdcd按观众在手机上看到的样子验收src/core/probe.tsx：在浏览器里测每段可读文字的实际位置（缩放、遮罩、透明度都算进去），超出平台安全区（promo.json的safe：状态栏、底部标题区、右侧按钮栏）或被画面边缘切掉就画红框；本来就要出画的装饰用<Free>/data-copy="free"标出verify第 5 关改为「短片在手机上读得到」：抽查第 0 帧（必须有字）、每个 cue 定住后的那一帧、转场中点、封面帧；promo-sheet用同一套抽帧；promo.mjs渲染前先跑这项检查，出片后导出out/<id>-cover.pngPACKS推出（「十套风格包」「06 OF 10」）；新加测试核对PACKS与磁盘上的风格包一致，并拦截手写的数量docs/principles.md新增第 8 条「按观众看到的样子验收，不按画布」；new-promo、review两个 skill 和 README 同步更新验证
npm run verify8 关全部通过（类型、24 个测试、3 种画幅渲染、确定性、短片安全区、短片确定性）node tools/promo.mjs：-14.1 LUFS，真峰值 -2.1 dBTP，LRA 2.9未改动（待定）
