Produce App Store and Google Play screenshots end to end in five steps — (1) App brief from the listing or a sentence, (2) Screens captured on a Release build with sim-use, (3) Look picked from a rendered catalogue of 30 styles or a reference set, (4) Sizes / platforms / locales, (5) Review page (brief + every headline) a teammate signs off before anything renders — then render with store-art, optionally generate mascots / stickers / backdrops with Codex, run the quality bar, upload with gpc / asc, and re-test copy after 30 days.
