+            The list of winners will contain at most `winners` entries per auction.
+            It may contain fewer or no entries at all if there aren't enough products with usable bids, that is,
+            a bid amount greater than the reserve price and belonging to a campaign with enough remaining budget.
+            Bids become unusable if campaign budget is exhausted, the bid is disqualified to preserve spend pacing, etc.
