Vertical 2:3 product-display background. Match the source image's overall composition, atmosphere, perspective, materials, and main display structures, while redesigning secondary decorative elements with related but visibly different shapes, positions, angles, and colors. Clean commercial stock-background quality. No watermark, logo, brand mark, readable words, letters, numbers, tiny edge text, UI marks, checkmarks, or disconnected white border. Create an airy pastel-blue sky with a few translucent bubbles and green-blue spheres at the low side edges, plus a soft rolling bright-green grassy hill along the lower third. Add only a few tiny blossoms; retain a large, clean open sky area for product placement.
