  "descriptionEn": "Shopping trolley with genuinely open tapered wire basket, rear nesting gate, lower wire tray, tubular chassis and four detailed swivel casters. For games and visualization; not validated for manufacture, structural engineering or 3D printing. Repeated static details are grouped by material and assembly; the procedural source retains the editable construction.",
