-- Driver: regression coverage for the Oak's lab chain reported broken:
--   * move menu / TYPE-PP box layout (screenshots)
--   * enemy faint slide ends with the pic gone (screenshots)
--   * the rival challenge fires two steps from the table (y==6),
--     no talking required
--   * leaving the lab after the fight takes the LAST_MAP exit mat
--     back to Pallet (previously asserted: no remembered outdoor map)
