Perf Concurrent Product 08

Performance test product 08 completes the small to medium product fixture for shop 20879048726. The copy gives the machine translation job a realistic amount of product description content, SEO text, option values, and publishable product data. It is intentionally bounded so the concurrent run remains low effort and interpretable. Together with the other imported products, this should move the shop closer to the target range without turning it into a large-shop stress test.
