Ads Agents: One Chat Shell and Meta Parity

The Google and Meta ads agents share one chat shell — drawers for brief, context, conversations, history and scope, and one composer with model and Tune menus. Meta caught up with Google: cited web research, paged history, and conversion and account-activity reads.

• Proposals render in order and never duplicate, and a follow-up never cancels a plan awaiting approval
• Quick prompts draft into the composer instead of sending
• One proposal card with before → after values, units and deltas
