SCSS fails to parse

[rgouveiamendes]

Bug description

I am getting the following erros after compiling a Reveal presentation:

Error adding css vars block Error: Expecting punctuation: "}" (2828:53)
    at InputStream.err (file:///opt/quarto/bin/quarto.js:48871:15)

    at Parser.parse_stylesheet (file:///opt/quarto/bin/quarto.js:49203:31)
The resulting CSS file will not have SCSS color variables exported as CSS.
This is likely a Quarto bug.
Please consider reporting it at https://github.com/quarto-dev/quarto-cli,
along with the _quarto_internal_scss_error.scss file that can be found in the current working directory.

Steps to reproduce

My CSS tweaks are in a file `personal.scss` such this.

## Hello World

Hi

Expected behavior

I would expect a no error compilation.

Actual behavior

What I've described above: an error in the compilation log and a scss file generated.
