Example

---
title: "Test"
format: 
  typst:
    keep-typ: true
    keep-md: true
---

```{r}
#| results: asis
knitr::asis_output("`#set page(flipped: true)`{=typst}")



Using `asis_output()` will not apply raw output here, because `options$results = 'asis'` us onlyfor LaTeX output

I think we need it for Quarto as the wrapping used will check for this value
