玻璃球里的斐波那契晶格

Clear glass sphere with soft clean specular highlights floating in front of a pure black backplate. Inside the sphere, a delicate nautilus Fibonacci spiral lattice with soft bevels hangs at the center; faint internal haze reveals gentle light shafts. Minimalist surreal photoreal CGI, mostly monochrome grayscale with a single cool cyan rim-light accent tracing the sphere's right edge. Centered eye-level 50mm framing, medium subject scale, calm pristine studio mood, soft backlight halo plus subtle overhead key. No text, no letters, no logos, no watermark, no fingerprints, no heavy caustics, no color clutter beyond the cyan accent. Vertical 9:16, high resolution, abstract product-still aesthetic.
