Use case: product-mockup
Asset type: Vertical ecommerce product display background, 2:3.
Prompt:
Regenerate a dark neon futuristic corridor product display background with triangular light portals, vertical 2:3. Keep a black and deep navy sci-fi corridor, glossy reflective floor, angled side wall panels, blue neon vertical strips, red accent floor lines, centered nested triangular glowing portals, symmetrical central perspective, and a clean reflective floor path suitable for product placement. Change triangle spacing, side panel angle, light strip positions, floor reflection, ceiling panel lines, portal color accents, and corridor depth so the result is related but not identical.
