corrinmain6969-hub/magic-background-remover ? reverse-engineered prompt

Build me a simple web app that lets me remove the background from an image in a few clicks.

I want to be able to upload a JPG, PNG, or WebP, have the app send it to Gemini with my API key, then show me the cutout with the background removed. After that, I should be able to preview the result and download the cleaned image. Make it feel fast and easy for people who just want quick product photos, profile pictures, or image cleanup without using a complicated editor.

Please keep the UI clean and straightforward, with clear upload, process, and download steps, plus a helpful message if the image fails or the API key is missing. It should run locally in the browser during development, and if you need to check current docs for Gemini or image handling details, look them up online.
