I did webdev for a long time, so yeah. If you want the story, I was looking into guix on asahi and ended up on https://www.asahi-guix.org/ which didn’t load anything, so I checked the page source and noticed the element.

Thanks. Not sure what's with the downvotes. That was a genuine question.

(I used to do a lot of web development and probably know dev tools better than most people here. However I almost never look at the DOM of a webpage I don't own)

		Text doesn't transmit tone well. FWIW I interpreted your comment as having somewhat accusatory intent, especially the scare-quoted "notice", for implying the author didn't just happen along his discovery and that he wasn't being fully truthful in his explanation of how he discovered this info.
