Integration
The reusable source is written to @components/product-card-1.tsx.
The registry also includes app/product-card-1/page.tsx as a complete preview route; an existing application can keep the reusable component files without adopting that route.
Example content is isolated in @components/data/product-card-1-data.ts (Product, products); replace those fixtures with application data rather than editing layout markup in several places.
