--   * StartMap's `farcall InitCallReceiveDelay`: a genuine World:setMap has
--     to arm the receive countdown off the game clock.
--   * CheckTimeEvents' CheckPhoneCall arm: with a contact in the book and
--     the countdown run down, a random call has to RING in the overworld --
--     the caller-ID page, the extracted bank $41 chat, the Click! -- and a
--     caller script's .WantsBattle has to arm its _READY_FOR_REMATCH event.
--   * The Pokegear's CALL entry: the callee's SCRIPT1 runs through the same
--     VM while the card keeps the screen.
