    // windows! This could *maybe* be worked around by making it a large iframe and covering it up, but then I would have to make the entire thing bigger, and figure out how everything
    // fits together, and then... well, look, I'm not doing it. I made this because I'm so lazy I want to sit back and watch Lichess TV all day and not even have to switch pages to
    // comment, so clearly I'm not going to put in that work. If someone else wants to do it, though, feel free, and I'd love to see your results!
