// ============================================================================
// Order status groups — which RAW `GET /admin/bookings` enums make up each
// operator-facing status the Orders page shows as a tab.
//
// Shared by the Orders page and anything else that counts orders by status,
// so a second definition cannot drift from the tabs an operator is looking
// at.
//
// ⚠ This is deliberately NOT the same taxonomy as queries.js's
// BOOKING_STATUS_TO_DELIVERY_STATUS, and the two must not be merged:
//
//   • Orders page — tracks the OPERATOR's workflow. "Assigned"
//     means the operator picked a rider, the moment assign-miler succeeds, so
//     miler_assigned counts as Assigned.
//   • Deliveries page (queries.js) — tracks the RIDER's engagement. Its "Accepted"
//     means the rider accepted, a deliberately later and narrower bar, so it
//     keeps miler_assigned on 'pending'.
//
// That split is explicit product direction — it was unified once and
// reverted. On Orders, "Assigned" is an operator action; on Deliveries,
// "Accepted" is a rider action, and the two screens must keep saying so.
