/// ONE APP, TWO VOCABULARIES
///
/// The two rider apps this one replaces disagreed about what a job is called:
/// the parcel app said **booking**, the meal app said **delivery**. Merging
/// them did not make either wrong — a rider collecting a consignment for the
/// hub is not delivering it, and a rider handing somebody lunch has not taken a
/// booking — so the noun follows the line of work and a rider only ever sees
/// the word he already uses.
///
/// These tests are the contract every screen reads through. Get them wrong and
/// a meal rider is told to "work it from Bookings", a tab he does not have.
