> honestly these are so obvious that I assume you viewed the website on mobile

The page is terrible UX on mobile too. After the random switch from dark mode to light mode I tapped what looked like a dark mode button and got a full screen about page with no close or back button, so I pressed my phone's back button but ended up back on HN. It turns out to navigate back out of the unexpected about screen you have to press what looks like a forward button (I think they're trying to indicate that it goes away to the right, but the thing is full screen like a full page navigation so that doesn't make sense).
