“ZIGZ”是使用 FontVibe AI 创作的水晶文字效果。从纯净宝石水晶中雕琢而成——钻石切割的刻面，绽放绚丽彩虹棱镜色散和奢华闪光。焦散光斑投落其下。

Create a 16:9 website hero key visual with exactly one rendered text string: “ZIGZ”. No other lettering, no logos, no badges, no watermark. Place “ZIGZ” centered horizontally and vertically, spanning 74% of the frame width and 29% of the frame height. Build a custom all-caps geometric display wordmark with broad, squared Z forms, even heavy strokes, tight optical spacing, sharp diagonal terminals, and a small central aperture in each G. The letters are carved from optically pure colorless gemstone crystal, not glass or plastic. Construct every stroke with precise brilliant-cut diamond geometry: a flat polished table face, stepped crown facets, a crisp widest girdle edge, and steep pavilion facets below. All planar junctions are razor-sharp knife edges. Use a deep midnight navy fading to near-black at the outer edges as a jeweler’s-vault background. A single hard overhead pinpoint spotlight produces near-white brilliance on upper table facets and saturated deep blue-violet shadow in lower pavilion planes. Show narrow internal caustic corridors traveling through each letter. At selected outer apexes, add clean six-point white sparkle flares. From several crown-facet edges, project sparse, sharply defined prismatic red, orange, yellow, green, blue, and violet fire beams into the surrounding darkness. Keep the rainbow beams thin and physically refracted, never hazy or neon. Add only a few dust-scale suspended particles catching the light. The wordmark floats 2 cm above a black mirror-polished obsidian floor, with a soft, fragmented crystal reflection directly beneath it. Leave at least 45% of the canvas as uncluttered dark negative space around the lettering. Front-facing camera, no perspective warp, ray-traced gem optics, high micro-contrast, 8k product-render precision.
