Use case: product-mockup
Asset type: Vertical ecommerce product display background, 2:3.
Prompt:
Regenerate a dark blue arctic landscape product display background with a glowing circular arch, vertical 2:3. Keep a deep night-blue sky with subtle stars, pale icy dunes or snow waves, distant low mountains, cool atmospheric haze, a low round illuminated podium in the lower center with a clean empty top, and a large glowing white semicircular ring behind it. Change ring diameter, podium thickness, dune contours, star positions, horizon depth, glow intensity, and foreground texture 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 unintended black edges. No readable text, no numbers, no Chinese characters, no English words, no brand logo, no trademark symbols, no people, no packaging. Polished 3D render, minimal futuristic luxury product backdrop, clean full-bleed composition.
