Yes. It does so trivially, but in the process it breaks the CSS for larger screens. I couldn't get it to get both to work at the same time in 5 minutes of trying. My modern CSS skills aren't good enough to quickly notice what the problem is, so it's beyond my horizon of caring (but I do encourage hints I could pass on to the AI).
It does fix it trivially, just in a way that causes regression on larger screens :).
As mentioned above, I don't care. It's sized correctly for the devices I use to play it, and I'm not going to put any more work into this. I mean, even junior web devs get paid stupidly high salaries for doing Responsive Web Design; I ain't gonna work on this for free.
(But I will accept AI-generated patches, or human-generated advice I could paste into the prompt to get a correct solution :P.)
