[DRAFT] Churn Radar

Nordwind's retention team was flying blind: churn showed up in the quarterly numbers long after the customer had already gone quiet.

We built a feature store on their existing warehouse, trained a gradient-boosted churn model, and wired live scoring into their CRM so at-risk accounts surface the moment behaviour shifts.

The model retrains nightly and pushes a ranked at-risk list into the tools the retention team already lives in.
