/// THE LIVE STOP SCREEN'S CONTRACT
///
/// One screen serves both legs — a kitchen counter and a customer's door — and
/// almost everything on it changes meaning between them: the destination, the
/// copy, the action, and the number under the Call button.
///
/// That last one is the dangerous one, because it fails silently. A rider at a
/// door taps Call, reaches the kitchen, and the screen looks correct
/// throughout. These pin who is being rung, per leg, and who the app *says* is
/// being rung — the two used to be decided in different places.
