thanks for your efforts and for checking out my prototype! i've pushed two commits that aim to improve the integration even a bit further; long-term we'll have to do some more cleanup work to make sure the standard label generator can be cleanly switched to Typst with a single config setting or so.

i'll also polish the draft some more, but i guess i'll open a PR for the other devs to take a look at all of this as well.

thanks again!
