Code review comment for lp:~deadlight/canonical-identity-provider/add-vanilla-and-sass

I'm not checking in the Vanilla-generated CSS, for some reason the CSS file for the existing content has changed. I'll just remove it from this build since I should be making no changes to existing styling.

Re: cherry-picking - we can do an audit of used components at the end of the project and just include css for what we're using.
