Description: Bag OEM/ODM lead-generation theme for XIAMEN UTOP INTERNATIONAL. Pattern-paper ground and ink type with a single kraft-derived accent sampled from real cut-panel material (hue band 30°, span 10°). Signature language is "The Seam": 8-SPI lockstitch dashes as every divider, cut-corner media frames echoing the sheared logo, and feed-dog motion (discrete steps(), never fade-up). Price-free ToB catalog with inquiry-first product pages, configurable homepage sections, floating WhatsApp contact rail. All copy and imagery managed from the admin.
