ParthJadhav/app-store-screenshots ? reverse-engineered prompt

Build me a screenshot generator for App Store and Google Play marketing images.

I want a web editor where I can upload real app screenshots, arrange them into a deck, add big headline copy, and preview everything on phone and tablet frames. It should let me work in a connected canvas so elements can flow across multiple screenshots, but also have a safer isolated mode for older projects. I need a sidebar to reorder slides, an inspector to edit text, layouts, screenshots, and small design details, plus autosave so I can close the browser and come back later without losing work.

Please make it export ready PNG bundles for the common Apple and Google Play sizes, including phone, tablet, and feature graphic formats. Support themes, multiple locales, and RTL friendly layouts if needed. Save the deck state to a JSON file and keep uploaded images in public storage so the project is easy to reopen and share. If you need to, look up current docs online for the best way to render exact screenshots and zip the exports.
