 * These exercise the webmail's ability to reflect *external* changes to the
 * mailbox — new deliveries, server-side reads/moves/deletes, and folder
 * creation — which is where "my counts are wrong / my folder didn't show up"
 * sync bugs live. Mutations are made over SMTP/JMAP and the assertions are on
 * the rendered UI.
