If more than one brand is reachable, call `list_brands` first and pass `brand` on every call.

Review audience saturation on Meta. For each ad set with spend in the last 14 days, compare reach growth vs spend growth - a flat reach with rising spend is the saturation signal. Use `get_performance` with platform='meta', entity_type='adset', date_range={"days": 14} for current reach and spend, then call it again for the prior 14-day window (compare_to_previous is not supported at ad-set level) to read the trend.
