AarjanAdhikari/Monex ? reverse-engineered prompt

Build me a modern currency conversion app called Monex that lets people quickly convert between currencies using live exchange rates.

I want a clean, easy to use interface where someone can pick two currencies, enter an amount, and instantly see the result. It should also show live rate updates and a simple chart or trend view for historical exchange rates so users can understand how a currency has changed over time. Make it responsive so it works well on phones and desktop, and give it a polished modern look with a dark mode.

Please make it fast, reliable, and straightforward to use. If you need to check current setup details or docs while building, go ahead and look them up online. Also include a basic development setup so I can run it locally, and make sure the app is ready to build for production.
