+// A customer-app booking is ONE pickup carrying N destinations — never N
+// bookings. `GET /admin/bookings` reports how many each row has
+// (`destinationcount`, `totalpackagecount`) without shipping the destination
+// array, which is fetched only when a row is opened.
+//
+// Every helper here has to survive three shapes of row, because all three
+// reach the Orders table at once:
+//
+//   1. The console running AHEAD of the backend that adds these fields, where
+//      `destinationcount` is undefined. Nothing may change for that row.
+//   2. An ordinary single-drop booking, which is most of them.
+//   3. A console-created booking, which has no bookingdestinations rows at all
+//      and reports 0 — distinct from 1, and rendered the same as case 1.
