As a reader of compliance documentation, I want the documents to be very accessible

While looking at the cloud.gov example I noticed that GitBook's light grey UI controls might not have enough visual contrast to conform with 508 standards. It'd be good to give this default template a basic accessibility review to check for other problems like that. We may also want to hide the default social media icons at top right, to minimize distraction.

We could update Compliance Masonry to add a custom CSS file to modify the GitBook theme to fix any issues.
