Prompt:
Regenerate a symmetrical deep-red futuristic tunnel with repeated rounded rectangular ribs receding to a brilliant white opening, bright white curved ceiling light bands, glossy red central runway and thin luminous floor-edge lines. Keep runway clean for placement. Vary rib spacing, tunnel length, light bands and reflections. Remove text, logos, watermarks and borders. No people or packaging. Polished cinematic 3D render, full bleed.
