✔️ This tests well, it's generating domains based on my username (sharpirate) such as shadysharpirate.wordpress.com, beardedsharpirate.wordpress.com etc.

This is testing well for me! I ran through free flow three times:

• First time I used a unique title with no special chars. That title was used as the domain.
• Second time I used the same title again. Domain was that title + a number.
• Third time I used the same title but inserted a special char. The domain selected was adjective + username.

I did notice that the at the end of the flow, the site wasn't launching correctly - it was continually redirecting back to launchpad. But I've confirmed this is just because the backend diff is missing some recent launchpad.php changes and just needs to be rebased. Going to approve this in any case as the backend diff is separate.

I did also tested the backend diff on it's own per testing instruction on that diff - just manually generating name combinations, and that's working well too.
