"""D4 Q1: trace packOpeningAnimationEnabled (atom 0x20e = 526) through the
settings switch FUN_18013c6d0 -> settings-struct field index -> the applier
FUN_18011dc50 -> gate byte offset -> IS_* key published by FUN_18006cc60.

HYPOTHESIS: atom 0x20e has an arm in FUN_18013c6d0 that stores into some field
index N of the settings struct; FUN_18011dc50 copies index N to a gate byte;
FUN_18006cc60 publishes that byte under an IS_* string key.

CONTROLS (must reproduce before trusting the new answer):
  friendlySeasonsEnabled -> field [0x16] -> gate 0x1fd3a -> IS_FRIENDLY_SEASON_ENABLED
  enableDraftMode        -> field [0x17] -> gate 0x1fd3d -> IS_DRAFT_MODE_ENABLED

Also dumps every string in the image matching PACK/ANIM/REVEAL/WALKOUT so Q2/Q3
have a target list.
