Part of introducing the revamped signup flow for the P2 project.
In this PR, we add the redesigned “site” signup step for P2.
Testing instructions
Navigate to http://calypso.localhost:3000/start/p2
and go through the flow. It should look and work fine. Try both in an incognito window (=> new wp.com account) and with your current wp.com account.
Unfortunately, no screenshots were provided by the developer.
