I rolled my own slide deck. Wasn't the best plan, it's really quite janky! Click to toggle the reader view or hover your cursor down to the bottom-left and click the Slideshow button there. There's another hoverable color mode button bottom-right for toggling light, dark and auto modes. Otherwise browse around with your arrow keys and enjoy the jank! It was made to look best at a 16:9 aspect ratio.
a.k.a. Light mode Vs Dark mode.
Or, why building both dark and light schemes together is easy, actually.
