I came to this conclusion as well. The README gives off some vibes but the sheer volume and writing style of the code comments is what really sells it for me. For example:
// Enhanced styling with column-specific classes and alignment
This sort of marketing-speak isn't what people typically put in their code, LLMs love buzzwords. It's not just this, it's everything, but hopefully you get what I mean.
The mindless code comments are a dead giveaway. It's always the same pattern of:
"a thing" <--- here is a thing
Generally a dev would clean these up, but when they don't it's a major red flag to me that it's just unreviewed vibe coded slop.
