Use case: stylized-concept. Reference image: bright blue sky, yellow daisy framing, and dark rock foreground only. Create a clean vertical 2:3 spring product background with a large clear blue sky, soft small white clouds near mid height, tall golden-yellow daisy-like flowers rising around the far left and right edges, and a low dark gray textured rock shelf spanning the lower center. Leave the rock shelf empty for product placement. Polished semi-realistic 3D illustration, sunny clean daylight. Remove the top watermark mark and all text. Change flower species, heights, petal shapes, rock texture, cloud forms, and leaf positions so it is related but not identical. No text, numbers, Chinese characters, watermark, brand logo, edge text, border, or white margin.
