I have to say having been a diehard latex person I tried out typst a few weeks ago and within a day I was producing beautiful documents with equations that were as nice as Latex and wildly less of a pita to type. I'm going to be using it for all my study notes from now on.

And a couple of docs I converted from latex went from about 10s to compile in latex to 10ms to compile in typst. I didn't think this would be a big deal since my docs aren't that big and I didn't feel like I was waiting long for compile but I'm already much more productive as a result.

Having said all of that, I have no idea why you would want pandoc or markdown involved. Typst (unlike latex) is really no harder than markdown to type, so you should just be using typst rather than markdown if that's what you want. Then you don't need pandoc in the mix at all.
