I'd love to use Typst for laying out machine-generated content, but as it stands, the Typst markup language doesn't seem trivial to emit.

Something like a stream of (ND)JSON could maybe work here, where e.g. (and I haven't thought this through!)

#set par(justify: true)

= Background
In the case of glaciers, fluid...

could become

["#set", "par", {"justify": true}]
["heading", "Background"]
"In the case of glaciers, fluid..."

or

Total displaced soil by glacial flow:

$ 7.32 beta  
  sum_(i=0)^nabla Q_i / 2 $

could become

"Total displaced soil by glacial flow:"
["Math", "7.32 beta   sum_(i=0)^nabla Q_i / 2"]

Is this a silly thought?
