At the service level, `rules.min_advance_booking` defines the minimum seconds before the start time a booking can be made. At the slot level, `scheduling_rule_overrides.last_bookable_sec` specifies the last bookable time via an epoch timestamp. If both are set, the slot-level rule takes precedence. Merchants must also validate booking windows on requests and reject those out of bounds with a `SLOT_UNAVAILABLE` error.\n"],null,[]]
