bryanjaybodino/KaraOkay ? reverse-engineered prompt

Build me a simple karaoke web app I can run on my PC and control from my phone over my home Wi Fi.

I want one page for the big karaoke screen that shows the lyrics and one page for a mobile remote that can connect to it, so I can start, pause, and control playback from another device. The two pages should talk to each other live on the local network, so please make the connection work through a websocket URL I can point at my computer’s IP address.

Keep it easy to set up and run locally, and make sure the main screen opens cleanly in a browser while the remote page works well on a phone. If you need to check current docs or best practices for anything, go ahead and look them up online. Also make the project runnable in a standard Windows setup, since I may open it in Visual Studio or host it on a local web server.
