Centered for me at my usual browser width, then jumps to the left when widened to make room for the single side note example. A note that, boo hiss, doesn't show up at all at narrower widths. Not that it was an important note, but we're talking principle here. My mini-gripe is the typography: While I'm typically a dark mode guy, thin fonts are a lot harder to read in dark mode. But I've seen worse.
