Exploration — Plan limit upgrade popups exploration for Apollo

A messy exploration of upgrade popups for Apollo. The cards try different ways to tell people they’ve hit a plan limit: Gmail-only mailboxes, a capped number of records, HubSpot pulls, a sequence limit spelled out per plan, A/B testing, and running out of credits, with a count and buttons to see or get more.

Most end with a strip of plans marked with crosses and checks, and a single button. A column on the right tries the same View Pricing Plans button over different lines of microcopy.
