Assemble an iMessage notification-cascade video ad (≈14s, 9:16) from a phone-on-desk plate + 3–5 messages — authentic Apple Messages banners composited in PIL (SF Pro text, green Messages icon, warm translucent-greige fill, soft shadow) spring in one-by-one at the BOTTOM and push the stack UP, a right-aligned Show-less/X pill rides above, the X clears the stack, then a serif end card resolves.

The free, deterministic renderer for the imessage-notification-cascade video ad format — the viral iOS trend where a phone lies face-up (the source: 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.
The creative calls are the user's, asked by the format recipe before any paid step; this renderer draws whatever the config holds.

With no bed, compose.py plays the pops + swoosh over silence; --no-audio is fully silent.
