## Public callouts

- Set one minimum margin rule; the app activates checkout enforcement for you
- Import COGS from Shopify, CSV, or manual entry and sync to metafields
- Dashboard shows the max safe discount per product, most at risk first
- Fail-open: products without COGS data never block a legitimate sale
