Shopify-aware components and utilities for custom React Router storefronts. Provides commerce building blocks so developers can focus on the shopping experience.

Reach for it when:
- Developer-maintained Shopify storefronts
- Custom shopping experiences beyond a theme

Worth knowing: MIT-licensed toolkit; Shopify's backend remains a managed service. This entry covers the supported React Router setup, not the framework-agnostic developer preview.
