I made a dark mode toggle. It tries to default to your preferred color scheme but you can override it if you accept a cookie. There is probably a better way to implement this that doesn’t require you to repeat the CSS rules but I’ll figure it out later.

Philosophy: my whole site here is on a four-color theme, basically black, white, and then light/dark variants of fuckboy teal. Toggling dark mode just flips black and white, then replaces the light/dark variants of fuckboy teal with the other.

Dark mode should work on the guestbook, too (or will once I push the update). But the trix rich text editor used by Ruby on Rails doesn’t really support dark mode, so there are still some uncomfortable pops of white.
