+  "summary": "Product attributes now flow from backend serializeProduct through the typed frontend Product interface and render as accessible badges on the product detail page. Type-safe: PRODUCT_ATTRIBUTES const matches backend domain enum; ProductAttribute type is derived from it. The Product interface gains attributes?: ProductAttribute[] (optional, no breaking change). ATTRIBUTE_LABELS provides Spanish labels for all 16 attribute values. ProductAttributes component returns null when no attributes, preserving existing page layout. Integration is a single self-closing tag after the h1. Typecheck and lint pass green.",
