Subject: [PATCH] Confirm registrants with a "You're registered!" banner
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After a successful public registration the registrant landed on the ticket
page with only a transient flash toast — no durable confirmation they were in.

Carry a `registered` flag to the ticket page on the success redirect; show a
green "You're registered!" banner above the ticket when arriving from a fresh
registration or a successful Stripe `checkout=success` return, but not on plain
return visits.
