name: Per-day price campaigns
overview: Shift Google price automation from one batch-wide campaign (cheapest day wins) to one campaign per stay night, with daily cron rolling the reach window forward (6 updates + 1 create per run). Property-level Hotel summary keeps the highest discount across the batch; legacy wide campaigns and nights that fall off the window are deactivated.
