Claude's 104 product demos: two clocks, a phoneme-timed mouth and one ffmpeg join

Reverse-engineers a batch of 104 Claude-made product demos and compares it with the site's own film engine. Covers recording tool runs with Playwright, drawing the cursor from logs, using Kokoro's phoneme timings for word budgets and lip sync, painting every frame from t, a seeded score, the ffmpeg join, and a contact-sheet gate before the batch.
