PricingService.seedVariantPrice (pricing owns pricing_variant_prices) is injected into CreateProductVariant via the pricing public index (R1-clean, identical to the cart→pricing cross-module write pattern). A single constructor covers all 3 variant-creation call sites. build-app hoists the pricing const above catalog registration — a pure construction reorder with no side effects. Seed is best-effort so variant creation never regresses.",
