I added a light theme for user-agents that support preferring light color schemes. Dark is still the default, because it’s the correct way to have a color scheme, despite people shouting at me on the internet from 2002 until the advent of dark mode that “dark themes go against biological fact.” How strange that the biological essentialism vanished overnight, almost as if it were never true.

While I was updating the stylesheet, I fixed some 2009-isms in it, like IE-specific rules and prefixed border-radius rules. This is the future.
