Hi,
I just wanted to suggest adding a flag to the config to discard the original syntax, avoiding code duplication in the CSS output. This would help keeping the output code small when not needed.
For example, the app may add a little snippet like this on top: document.documentElement.classList.toggle('is-dark', matchMedia('(prefers-color-scheme: dark)').matches)
Please let me know if a PR would be welcomed.
Thanks!
