	// add-interview / add-deadline flows can be exercised without
	// hitting Google. When nil, the production path runs the real OAuth
	// + Calendar API.

	// InboxClientFunc lets tests inject a fake inbox.Client (no real
	// IMAP, no real network) so the poll flow can be exercised

	// IMAP client.
