Prompt

Abstract architectural minimalism: a single translucent cobalt-blue crescent suspended from a nearly invisible filament in a vast warm-white gallery alcove with a smooth soft-limestone floor. Asymmetrical composition, crescent floating near the upper-left quadrant amid expansive natural negative space. Diffuse overhead illumination casts a faint, curved pool of blue-tinted light below. Clean, quietly futuristic atmosphere, restrained detail, controlled visual noise, no text, watermark, logo, border, UI, or interface elements.
