render-imessage-chat

The free renderer for the imessage-chat video ad format — a texting-thread reveal where a friend-to-friend conversation animates in on a phone (typing indicators, composer typing, bubble pops, smooth auto-scroll) and lands on a designed brand end card. Deterministic Playwright + ffmpeg assembly; no generative video of the UI, so bubble text and the wordmark stay pixel-crisp.

This capability is the generic assembler — the template recipe (DB) supplies the per-brand thread, product image, and end_card config, and gates the paid calls (product image → create-image-fal, music bed → create-music-elevenlabs) to their own capabilities. It bundles the iMessage-mockup HTML generator + the send/receive SFX so a chat render is self-contained and $0.
