- it uses VSCode grammars and themes, which is awesome.

- it’s got some really cool extensions like Shiki Twoslash[1], allowing VSCode-like type hovers and type error demos. I’ve heard this can work without client-side JS but haven’t had the opportunity to check that out just yet.

- with some effort, you can extract the inline styles to a stylesheet and support pure CSS dark mode (note to self: clean up and open source my implementation of this).
