Budget rescue: 6 ad slots, 4 page-loads, one budget

A page with 6 ad slots wants to call selectURL for every slot. Without saved queries that's 6 × 256 = 1,536 budget per page-load — you run out in 3 reloads. With { savedQuery: true } reuse, 5 of the 6 slots are free after their first hit. Press the simulation buttons to compare.
