Use case: product-mockup
Asset type: Vertical ecommerce product display background, 2:3.
Prompt:
Regenerate an iridescent ornate frame product display background with blue sky and clouds, vertical 2:3. Keep a soft blue sky with fluffy white clouds, pale pink-white satin or silk fabric drapery, bright sparkle highlights, and a centered pearly translucent oval-rectangular decorative frame with clear open sky visible through the opening. Change frame ornament details, pearl positions, frame outline, fabric folds, cloud placement, sparkle positions, and iridescent color shifts 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 monograms, no packaging, no people, no objects blocking the frame opening. Polished 3D render, glossy cosmetics or jewelry-style product backdrop, clean full-bleed composition.
