This PR is blocked because it contains a minor changeset. A reviewer will merge this at the next release if approved.

[Princesseuh]

Haven't decided of an API shape for this usecase yet in Sätteri. It'll defnitely be supported soon because it's a common request, so I expect it before the next major for sure.

[ArmandPhilippot]

I left a nit for the changeset, but this LGTM.

I was also hesitant to mention CSP there... Because as Ema pointed out, CSP users might not want to test it as Shiki is not compatible. But maybe this is something to say in the blog post rather than in the changelog.

[Princesseuh]

Fwiw, I think we'll be shipping Prism support like, the day after or so. It's not very hard or anything.
