Absolutely vibe coded, I'm sure I disclosed it somewhere on the site. As much as I hate using AI for creative endeavours I have to agree that it excels as nextjs/vercel/quick projects like this. I was mostly focused on the curation of the tropes and examples.
Believe me I've had to adjust my writing a lot to avoid these tells, even academics I know are second guessing everything they've ever been taught. It's quite sad but I think it will result in a more personable internet as people try to distinguish themselves from the bots.
