Use case: product-mockup. Reference image: minimalist geometric composition and material language only. Create a clean vertical 2:3 high-key product display scene with a low white rectangular plinth in the lower center, a wide rounded pastel-lavender arch in the back right, a smaller icy-pale-blue rounded arch at back left, and tall translucent ribbed glass panels at both side edges. Bright soft studio daylight, subtle refraction and gentle floor shadows, refined contemporary 3D render. Keep the plinth empty. Change arch proportions, ribbed panel spacing, glass texture, pastel hues, and shadows so it is related but not identical. No text, numbers, Chinese characters, watermark, logo, trademark, tiny edge text, border, detached white edge, or corner symbol.
