Perf Concurrent Product 01

Performance test product 01 is a lightweight everyday item with realistic merchant copy for machine translation testing. The description includes product positioning, usage details, material notes, care guidance, and customer-facing language that resembles catalog content. Use this fixture to add moderate translation volume while keeping the shop small enough for a concurrent smoke test. It should exercise product title, product body, option values, and SEO metadata without creating a large-shop workload.
