// The in-flight set behind "connecting…": whoever opens a bank session — the

// one pending set until the open settles, and the row reads exactly that.
// The bug this pins: the reopen path never marked its dials, so a reopening
// bank spent its whole window as "hasn't connected yet" over a connect button.
