Search in HN for Typst and you'll see this link is routinely posted and as little as three months ago got nearly 200 comments.

There is overlap, with creating whole documents, but I can imagine at some point one could use Typst inside Quatro. (Like using Typst inside Obsidian.)

Yes, Typst is fully supported as an output language of Quarto.

Exceptions: you’ll need extensions for slides, some layouts. No books support, yet.

[I work on this.]
