Font-weight name incompatibility in Typst

[kazuyanagimoto]

Bug description

In brands.yml, if I specify the font-weight semibold, I got the following error from Quarto

ERROR: Validation of YAML front matter failed.
ERROR: In file Untitled.qmd
(line 11, columns 15--22) Field "weight" has value semibold, which must instead be one of: `100`, `200`, `300`, `400`, `500`, `600`, `700`, `800`, `900`, `thin`, `extra-light`, `ultra-light`, `light`, `normal`, `regular`, `medium`, `semi-bold`, `demi-bold`, `bold`, `extra-bold`, `ultra-bold`, `black`
10:       family: Roboto
11:       weight: semibold
                 ~~~~~~~~
12: ---
ℹ Did you mean semi-bold?

However, if I specify the font-weight semi-bold, I get the following error from Typst

[typst]: Compiling Untitled.typ to Untitled.pdf...error: expected integer, "thin", "extralight", "light", "regular", "medium", "semibold", "bold", "extrabold", or "black"
    ┌─ Untitled.typ:292:48
    │
292 │ #show heading: set text(font: "Roboto", weight: "semi-bold", )

Here, we can see the incompatibility of the font-weight names.

Steps to reproduce

This is a minimal example.

      weight: semi-bold

Thanks for the report!

As a temporary workaround until this is fixed, you could use 600.

Looks like we are just passing weight through, when we need another _quarto.modules.typst.css conversion function for weight, as Typst does not have the dashes or the synonyms.

Probably worth a backport.
