Feature Request: Support BeerCSS variables as export format

[bjmc]

Is your feature request related to a problem? Please describe. It's wonderful that you support several different export formats already, but the "CSS" option requires quite a bit of finagling to get it into a format that is accepted by BeerCSS as variable overrides for its color and font settings.

Describe the solution you'd like If this tool could export font and color preferences in the form of CSS variable overrides with the names expected by BeerCSS that would save me and others the hassle of reformatting them.

Describe alternatives you've considered I can ask an LLM to translate the format or write my own reformatting script.

Additional context BeerCSS is a popular lightweight CSS framework that implements Material Design 3.
