I would love an option to opt into something like "reader mode" but maybe not quite so restrictive. (I can use some custom CSS to highlight code and some JS for interactive examples. Right now I need to worry about the user's contrast preferences, light/dark preferences. Decide if I want to force a decent font or end up with the user's default (which probably sucks). I need to decide the text size (because their default probably sucks) and decide how wide the reading area should be. What a mess to try and just pick something that the user wants.
