Made some initial progress on this... the current invision prototype contains some placeholder screens to account for the Testpilot experience, specifically the detail page and installation flow, with the inclusion of the promotional carousel of features...

I spoke about this with @BrianNJones yesterday, and we need to decide on the appropriate content strategy for both the test pilot screens, as well as the depth of potential space for product marketing within our welcome and first run experience... I'm worried that the default test pilot experience may be overkill for our needs.

I also plan to update our lucid chart to better reflect our beta offering.

If there's anything else I'm missing, please let me know, @sandysage
