Blog housekeeping
I've added a light theme to the blog's CSS which should be automatically selected if your system is set to use light mode. The original dark theme will be selected if your system is set to use dark mode.
This is something that improves accessibility, but there's also a practical reason: I myself use light mode. Like many folks with astigmatism, I find dark mode more difficult to read. The effect is worse with high contrast. I initially went with a darker color scheme for the site because I was going for a specific aesthetic, but chose a low contrast set of colors to minimize the impact. That was okay for a while, but I realized that I want a blog I can actually read even when my eyes get tired. And if it bothers me, there are almost certainly other people it bothers as well.
The new theme uses a paper-inspired color scheme to match the logo and overall site design. It's the sort of color scheme that I've started using in a lot of my text editors as well; I find it incredibly comfortable to read. The links are a dark red: an homage to my favorite color of fountain pen ink. I'm really pleased with how it came out.
