render-imessage-cascade

The free, deterministic renderer for the imessage-notification-cascade video ad format — the viral iOS trend where a phone sits on a desk and Apple Messages notifications STACK IN one after another. The signature mechanic is the bottom-up push: each new banner springs in at the bottom (nearest the phone) and shoves every existing one UP a row; the iOS grouped "⌄ Show less / ✕" pill rides above the stack; the ✕ clears the stack; then a serif end card resolves.

This is a DETERMINISTIC composite — no generative video of the UI. Authentic iMessage banners are drawn in PIL and animated in FFmpeg over a Ken-Burns plate, so the notification text + wordmark stay pixel-crisp (a video model would smear type). The template recipe supplies the per-brand plate, notifications, and end_card config and gates the only paid steps — cleaning the plate (→ create-image-fal) and the music bed/pop (→ create-music-elevenlabs) — to their own capabilities. This capability itself makes no paid calls.
