Build me a cross platform karaoke app that turns a computer or Raspberry Pi into a home KTV setup. I want it to open a full screen player on a TV or browser, then let people join from their phones by scanning a QR code so they can search songs, add them to a queue, and control playback without installing anything.

It should support YouTube karaoke songs and local media files, and have a simple admin mode with a password so the host can manage the queue and settings. I’d also like pitch shifting for songs, a fun random scoring feature, and a clean interface that works well on mobile and desktop.

Make it easy to run on macOS, Windows, Linux, and Raspberry Pi, with a Docker option too. If you need to check current docs or best practices while building it, feel free to look things up online.
