Background (Draft)?

[ondohotola]

Is it possible to have a background?

I like to have something like

#set page(
   background: rotate(
      45deg,
      text(
         5em,
         fill: mygrey
      )[Draft]
   )
)

This template currently uses the background layer for the folding marks and the hole mark. But it should be possible to add an option for this in the template:

#show: letter-simple.with(
  foreground: [Lorem ipsum],
  background: [Lorem ipsum],
  
  // ...
)
