synqronlabs/gla-qrify ? reverse-engineered prompt

Build me a clean little web app that lets people create QR codes from text or links in the browser.

I want a simple page where someone can paste in something, see the QR code update right away, and then download or save it as an image. Make it feel polished and easy to use, with a nice layout that works on mobile too. If it makes sense, add a few basic controls like changing the size, color, or error correction, but keep the experience straightforward.

Use whatever modern frontend setup is already in the project, and make sure it runs smoothly in development and builds cleanly for production. If you need to check current docs for the QR code library or any related details, go ahead and look them up online.
