nyxvrel-8080/nyxvrel-420 ? reverse-engineered prompt

Build me the app in this repo from scratch.

I want a clean TypeScript project with a simple src folder based setup, wired so it runs and builds without me having to figure out the tooling. Make the code easy to understand, add whatever basic entry point and structure are needed, and include a small example of the main functionality so I can see it working right away.

If anything is unclear, use sensible defaults and look up current docs online if you need to. Keep it lightweight, tidy, and ready for me to start editing.
