This should be a resource people building POCs can leverage to correctly build these UIs with the compass theme and components. It can be WIP draft, but at the end of the epic, we should have some docs hosted on our staging site that we can send along to product teams running experiments.

• where do they get the requisite style sheets?
• which new components/variants/classes should they be leveraging?
• can they leverage an application context to turn on/off glass or other compass related features?
