Is it possible to use this theme with quarto websites?

Dear @xriley

Quarto websites are a way to build websites using quarto documents, which are a great way to produce content that combines text and executable code (R or Python). Quarto websites offer an easy way to integrate a number of bootstrap themes described https://bootswatch.com by simply editing a line in a configuration YAML file, but I'd like to try to use your DevConf theme in a quarto website. This is what I did, unfortunately without success:

$ quarto create project website test
? Title (test) › Test
Creating project at /data/genomics/rcastelo/doc/organization/EuroBioC2025/Website/test/test:
  - Created _quarto.yml
  - Created index.qmd
  - Created about.qmd
  - Created styles.css
? Open With › (don't open)
$ cd test
$ ls
about.qmd  index.qmd  _quarto.yml  styles.css
$ cp -r ../../DevConf-Theme/assets . ## assuming I clone the DevConf-Theme repo two levels above

Then I edited the YAML configuration file _quarto.yml as follows:

project:
  type: website

website:
  title: "Test"
  navbar:
    left:
      - href: index.qmd
        text: Home
      - about.qmd

format:
  html:
    theme: assets/scss/theme.scss

But when I try to render this default minimal website, I get an error:

$ quarto render
[1/2] index.qmd
ERROR: The file /Users/rcastelo/sandbox/test/assets/scss/theme.scss doesn't contain at least one layer boundary (/*-- scss:defaults --*/, /*-- scss:rules --*/, /*-- scss:mixins --*/, /*-- scss:functions --*/, or /*-- scss:uses --*/)

Do you think is it possible at all to use the DevConf theme in a quarto website?

Thanks!
