I created a new Vendor/theme where, in the theme.xml, i referenced the Magento/luma theme. As i understand it right, the fallback should now grap styles from the luma theme and my new theme should fully look like luma.
What actually happens is
CSS compilation from source variable @font-family-name__base is undefined in file in pub static
styles-m.css after reload FE or even after
php bin/magento setup:static-content:deploy.
So it seems that the compilation is trying to use the right files but cannot process variables.
Is that a behavior which is already spottet somehow, did i something wrong?
