euphydev/qrcode-geneditor ? reverse-engineered prompt

Build me a clean QR code generator and editor in Next.js.

I want a simple page where I can paste in text or a link, instantly generate a QR code, and then tweak it before downloading. Let me change things like the colors, size, and style, and see the QR update right away as I edit it. Keep the interface modern, easy to use, and mobile friendly.

Add a clear download option so I can save the QR code as an image. If it helps, include a few sensible presets and make the default experience super straightforward for someone who just wants to make a QR code fast. Use the existing Next.js app structure, and look up current docs online if you need to.
