Thanks for sharing, looks really cool! Especially with how prevalent markdown is.

Hopefully this isn't too off topic/thread derailing:
As a longtime LaTeX enjoyer, lately I've become increasingly infatuated by Typst. With Excalidraw quickly winning my favour as well ...
However I find myself daydreaming of some of Obsidian's powerfull features for knowledge graphing/"second brain"-ing, but given various reasons, never successfully convinced myself to use it. (Primarily: markdown seemingly a bit too simplistic for my preference, and Obsidian, to my knowledge, not being open source(?))
Instead I've tried some alternatives, each with excellent ideas, unfortunately none really hitting home with my wierd brain. e.g. Zim, LogSeq, SiYuan, ...

As such I'm curious to hear about others' setup, and thoughts. - Is Some(Quarkdown + Obsidian) perhaps what I've truly been longing for for?
