Use case: product-mockup
Asset type: Vertical ecommerce product display background, 2:3.
Prompt:
Regenerate a minimalist white futuristic arch tunnel product display background, vertical 2:3. Keep a clean white and pale blue sci-fi tunnel with layered semicircular arches, glowing ring light bands, soft haze, centered symmetry, bright vanishing point, and an empty smooth foreground floor or podium area for product placement. Change arch spacing, ring thickness, panel divisions, glow intensity, floor curvature, side rib positions, and haze density so the result is related but not identical. No readable text is preserved. Remove watermark, logo, corner marks, tiny edge text, fake text, dirty borders, disconnected white margins, and black edges. No readable text, no numbers, no Chinese characters, no English words, no brand logo, no trademark symbols, no signage, no people, no packaging. Polished 3D render, minimal premium technology or skincare display background, clean full-bleed composition.
