Author here. This post arose out of a recent thread on the Hugo Discourse:

BTW, there's a glitch in your code snippet syntax highlighting; in Light mode, the 'p' selector is remaining an unreadable yellow.

		Whoops. Thanks for the catch. I was trying to trim down some of my CSS the other day, but inadvertently forgot to leave my `--cyan-700` variable. The yellow you saw was supposed to warn me, "Hey, you missed one!" but I apparently missed that one. :-/ Fixed.

Good call out from that thread is he's trying to get a small change in esbuild added to help with this as well.

		Yes; hope that gets blessed. We shall see.
