• AI Overviews report: a new dashboard under `/app/ai-overviews` that surfaces, for every tracked property, which of your top-ranking queries currently trigger a Google AI Overview, the share of your tracked queries that have one, and how that share is trending week-over-week. Data is pulled from SEMrush so you can see AI Overview exposure alongside the rest of your GSC metrics without leaving the app.

Changed

Fixed
