Is your feature request related to a problem? Please describe.

In debug mode, vars should be more explicit.

Describe a solution you'd like

Instead of:

:root {
    --x3dc7yf: #000;
    --x1f68uuh: #22005d;
    --xa37eq0: #381e72;
}

I would love to see:

:root {
    --x3dc7yf-primary: #000;
    --x1f68uuh-secondary: #22005d;
    --xa37eq0-tiertiary: #381e72;
}

Yes something like this is planned for the future.
