ValoSpectra/Spectra-Frontend ? reverse-engineered prompt

Build me a clean frontend for a Valorant tournament overlay that shows live match info for viewers in a polished, easy to read way.

It should pull game state from a server every 100 milliseconds, then display things like the current weapon, credits, shields, and team info in a stylish broadcast overlay. I also want it to be configurable from a JSON file, so I can point it to my server, set a redirect URL, add sponsor images, and customize attacker and defender colors without touching the app code.

Please make it easy to run in a browser and easy to host with Docker. If you need to check the latest setup details or best practices, look them up online. The finished result should feel like a production ready esports overlay, not a plain admin page.
