PMax placement & brand exclusions

Audit my Performance Max campaigns. Pick the highest-spend PMax campaign first (or ask me to choose one if I prefer). For that campaign: (1) pull the placement report for the last 30 days and surface every wasteful placement (high impressions with zero conversions, low-quality apps/channels, anything irrelevant to my offer) — don't cap the list, sort by wasted spend, (2) check whether brand exclusions are configured and recommend every brand worth adding to the PMax brand exclusion list, (3) preview the placement and brand exclusion mutations, and wait for my confirmation before executing. After this campaign, ask whether to continue with the next-highest-spend PMax campaign so we cover the whole account.
