We now have dark mode! You can toggle it in the footer. It will also respond to your OS preference if you have one set.
Sorry it took a while, I iterated into through a few different approaches before arriving at the current one. In contrast to the first approach I took, this one allows users who aren't signed in (shame on them) to get dark mode and prevents the dreaded light mode flash given we use SSR.
What I'll be working on next
