Seems to me from reading the deleted text file[1] like the author[2] used an LLM to get feedback on how to improve their own code. That isn't at all what "vibe-coding" usually means, and I say that as a complete AI hater myself.

Or do you have some "smoking gun" evidence?

I think the setup screen is a really nice touch and not something an AI would come up with.

[2] or someone else? it keeps using the phrase "your friend"
