Vertical 9:16 realistic 3D product display image of an A-frame wooden folding stepladder centered on a pale gray-white seamless background, shown at a slight side angle. The ladder is made of distressed dark brown wood with visible grain and wear; it has a rectangular top platform and four lower steps, each lower step with a dark gray-black rectangular anti-slip pad in the center. The thick wooden side rails are secured with round metal screws and rivets, with a rust-colored metal hinge connector near the upper section and crossed wooden braces at the rear. Soft studio lighting, full view of the ladder structure, no people, no text, clean background.
