Thanks @JusticeMatthew! I added a changeset and this looks good.

We’ll merge it when we’re ready for our next minor release!

little nitpick, otherwise looks superb! 🚀

Does this affect #1885 in any way? Could we close it or should we still take a look at that?

Good question. The intention of that PR still stands: that these styles maybe belong in the Markdown styles rather than the reset. But I honestly lost the context for it, so can’t remember whether we should do that or not.
