-- Parity: the Rocket Hideout lift gates (#372).
--
-- Oracle: scripts/RocketHideoutB4F.asm RocketHideoutB4FDoorCallbackScript
-- stamps $2d over the lift doorway (lb bc, 5, 12) until CheckBothEventsSet
-- EVENT_BEAT_ROCKET_HIDEOUT_4_TRAINER_0 / _1, then plays SFX_GO_INSIDE and
-- writes $e; scripts/RocketHideoutB1F.asm is the same shape with $54 at
-- lb bc, 8, 12 over EVENT_BEAT_ROCKET_HIDEOUT_1_TRAINER_4.  The callback
-- runs whenever BIT_CUR_MAP_LOADED_1 is set, which home/trainers.asm
-- EndTrainerBattle does, so the gate opens the moment the last guard falls
-- rather than on the next map load.
--
-- The .blk layouts ship both doorways open, so a cache whose closedDoors
-- predates the two rows left the gates open all game: FieldDefaults has to
-- seed them the way it seeds the PrintTrashText bins.
--
-- Self-contained: `luajit tests/parity_hideout_gate.lua`; also globbed by
-- tests/run_tests.lua.
