+	// Without an ORDER BY the row order is unspecified — Postgres returns heap

+	//
+	//   1. The newest booking sits on the LAST page. The console drains a
+	//      bounded window, so once pickupbookings outgrows that window a
+	//      just-created customer-app booking can never reach the Orders page at
+	//      all. It is written correctly and is simply never fetched.
+	//   2. OFFSET pagination over an unordered result is not stable: the same
+	//      page can return different rows across two requests, so draining pages
+	//      can duplicate and skip rows well before that threshold.
+	//
+	// bookingid rather than createdat: it is the primary key and unique, so the
+	// sort needs no tiebreaker and the paging cannot wobble between equal
+	// timestamps. It also matches the order the console already sorts into
+	// client-side, so page 1 is the newest page by both definitions.
