Tirthkapatel/Croper ? reverse-engineered prompt

Build me a simple web app called Croper that lets people upload a photo, crop it to the size they want, and download the finished image easily.

I want it to feel clean and quick to use, with a straightforward page where someone can pick an image, adjust the crop by dragging or resizing, and see the result before saving it. Make it work well on desktop and mobile, and keep the design modern but minimal.

If the project already includes any basic sign in or account related parts, keep those working, but don’t overcomplicate things. Also include the privacy and terms pages in a simple matching style so the app feels complete.

Use the existing project structure and make sure the app runs smoothly when deployed. If you need to check current docs or best practices for any library you use, look them up online first.
