"""What sets the gate bytes, and what are they born as?

The IS_* keys read single bytes in a contiguous block inside FutDataManagerImpl:
  0x1fd2e tradingEnabled   0x1fd2f storeEnabled  0x1fd30 storeEnabled_JP
  0x1fd3a friendlySeasons  0x1fd3b tournamentQuit  0x1fd3c processingState
  0x1fd3d draftMode        0x1fd3f storyModeReward  0x1fd40 returningUserRewards
These are NOT the int fields the /settings parser fills, so something copies
across. Two questions, and the second is the one that decides whether an empty
configs array blocks Seasons:

  (1) who WRITES these bytes (the applier, and the constructor default)
  (2) what value does the constructor give them

CONTROL: 0x1fd2f storeEnabled. Its screen works today under an empty configs
array, so whatever the ctor gives it is a non-blocking default, and any other
byte born the same way is equally non-blocking.
