// StaffShifts is a working window at one outlet.
//
// Separate from `ridershifts`, which already exists and was the obvious thing
// to reuse — but is the wrong shape twice over. It carries delivery economics
// (`basefare`, `fuelcharge`, `additionalkm`, `firstmilecharge`) that mean
// nothing at a counter, and it is scoped by `applocationid`, a city, where a
// shop's hours belong to the shop. A supermarket in Selvapuram and one in
// Gandhipuram do not open at the same time because they share a city.
//
// A person is assigned exactly one of these via `app_users.shiftid`, which is
// the column that already existed. That makes a shift a *template* — "the
// morning shift" — rather than a roster of dated assignments. A roster is the
// richer model and the one to reach for if per-date planning is ever wanted;
// this is the smaller thing that answers "who is on the early shift" without a
// second table and a second screen.
//
// Informational. Nothing refuses a bill rung outside a shift: the terminal has
// never been run against this, and a cashier locked out mid-queue by a clock is
// a worse failure than a bill filed against the wrong window.
