Build me a small JavaScript project that handles voice and audio preview files for a game or chat app.

I want it to play a couple of built in audio clips like a join sound and a maintenance sound, and it should also support a folder for voice previews that can be generated or organized from scripts. There should be a main entry point that ties everything together, plus a few helper modules for things like runtime fixes, countdown behavior, shard handling, and a portal style audio engine if that makes sense for the project.

Keep it simple and working, with clear code that I can run locally and extend later. If you need to look up current docs online for any audio or Node details, go ahead. Please make sure the project structure is clean, the scripts are wired up, and the existing mp3 assets are used properly.
