/// The two are different games to coach. A twelve-big-blind stack is a push-or-fold spot at a
/// tournament and a player who has lost some of a buy-in at a cash table; a small pair facing a
/// raise is a fold at a tournament table that will be short in an hour and a call at a cash table
/// where the money behind pays for the times it hits. So the catalogue of habits, the rating
/// scale and the assessment's arrangements each come in two editions, and every reader of them
/// asks which edition through `LeakCatalogue.format`.
///
/// It is a process-wide setting for the same reason `AppVariant.current` is: one build is one
/// product, chosen once by the app shell before the first screen. The suite and the command line
/// run the tournament edition unless a test says otherwise, and the suite resets it before every
/// suite so a cash test cannot leave the switch thrown for the next one.
