import default variables into app.styl

[Zeitvertreib]

I want to use $grey-1 in my app.styl file. (and all the other variables)
How can I import those? (documentation says only how to uses them in *.vue files)

thanks

edit:: especially I want to apply helper classes like q-mx-sm

I only know how to import them in the style section of vue files after setting the lang=“stylus”, thus:

// “variables” is a Webpack alias injected by Quasar CLI
@import ‘~variables’
