Header styles inclusion like it done in frontend-app-learning - https://github.com/openedx/frontend-app-learning/blob/master/src/index.scss#L7

It can be useful, for example, for the potential using of cookie banner

It makes sense, but I wonder what the impact is, visually. I can find some header-specific CSS here, and I'm worried that bringing in the default styles will break them, somehow.

Can we get before-after screenshots?

[mphilbrick211]
