amitraj02/BTC-alert ? reverse-engineered prompt

Build me a simple Bitcoin price alert app that checks the live BTC price and tells me when it goes above or below a level I choose.

I want a clean page where I can set an alert price, see the current Bitcoin price, and know whether an alert has already been triggered. It should feel lightweight and easy to use, with a basic dashboard style and clear status messages.

If it makes sense, include a way to run it as a small web app that can be deployed easily, and make sure it works well in a hosted environment. Keep the setup straightforward, and use current docs online if you need to. Please make the whole thing feel finished and usable, not just a demo.
