The article and parent talk mostly about layout in terms of rectangles and subdividing those into smaller rectangles. The basics like Box and Flex layout are pretty simple. Once you start adding constraints like min/max size and relative sizes it becomes more complex but still manageable. You’re still only reasoning about rectangles and their constraints. Adding rendered text in the mix increases complexity immensely. Determining the size of rendered text is a very complex problem space in itself involving fonts, dpi, text flow, code points, LTR/RTL, ligatures and more. It’s not just rectangles anymore.
