Surreal speculative environment painting of levitating glass seed-vault monoliths threaded with faint luminous veins, suspended within a vast subterranean salt cavern filled with drifting mineral dust and distant mirrored pools. A wide asymmetrical composition places a solitary foreground monolith off-center against receding cavern chambers. Smoky indigo, oxidized teal, and pale amber palette; soft radiance refracted through translucent stone and reflected across the cavern floor; mysterious, otherworldly atmosphere, controlled visual noise, no text, watermark, logo, border, UI, or interface elements.
