ACUL style not displayed properly (style overwriten by style prop in html tag)

After following the ACUL documentation and setting up the pipelines etc..

the universal login page still has the default branding styles and not the custom styling.
the files are correctly served and the .css file form the cdn contains the necessary styling but the parent login screen html tag has a style that overrides the ACUL .css styling.
when i delete that style. the underlying custom ACUL theme does show up. so i am a but confused.

any help is appreciated.
