Maybe this will show all the React/Next.js/Server components haters that you can use them to very quickly build pages that are very performant (though used stack isn't that important anyway, the result depends more on the user's effort and attention to details).
Well, if you use CSS blur and load even the most simple HTML page on old Android phone or full-screen on 4K screen, lag happens, but that's orthogonal to what I meant.
