A bit of a tangential meta comment, but it's refreshing to see a cool website in 2024 like this, all content no fluff. I'm surprised to see it still using frameset. But also sort of sad that there's currently no HTML5 equivalent to have resizeable panels like this without messing with javascript, mouse events, and so many edgecases. Frameset still works in all browsers, so I suppose you could can just use that, although it's been deprecated for almost 20 years now. I understand that the purpose of HTML is not to support such functionalities, but CSS could have filled the gap. The closest we ended up getting was "resize" but it only affects one element.
