App Store Screenshots — capture → frame → upload

Battle-tested end to end on a shipping game (SAPPER, 2026): 7 shots × 10 languages × iPhone + iPad = 140 frames, replaced across 39 App Store Connect locales and resubmitted for review in one day.

The philosophy: App Store screenshots are marketing frames, not raw UI — a big localized headline over a device mock containing a real, localized, real-data capture. Keep three independent layers so each can change cheaply:

1. Raw captures — slow to make, often not regenerable (live data, daily seeds). Archive them in git.
2. Captions + design config — one JSON for all locales and shots.
3. Compositor — scripts/generate.py re-renders every frame in minutes after any copy or design tweak. No recapture needed.
