“S”是使用 FontVibe AI 创作的液态玻璃文字效果。圆润的流动液态玻璃字母，透明水蓝色，带湿润光泽高光和柔和内部折射，背景是浅薰衣草到蓝的渐变。

Molten glass mid-flow physics: glossy wet surface with intense white specular highlights tracing maximum curvature points. Semi-transparent material with clear-to-blue-teal color gradient — shallow edge regions show faint blue-green tint, thick central volumes show deeper refractive depth. Internal caustic light patterns scatter within the glass body. Soft overhead diffused key light creates strong specular crowns while allowing the glass transparency to breathe against the background. Background: soft pastel gradient — pale lavender to ice blue — clean and airy, maximising glass transparency, refraction colour, and internal caustic visibility. Apple Vision Pro material aesthetic — premium, translucent, organically three-dimensional. Default drip rule: letters are solid volumetric glass forms — no drips, no liquid trails, no elongated drops hanging from letter bases, no actively flowing liquid effects. Exception: if the selected font explicitly describes drip, flow, or liquid-trail effects, follow the font description exactly — font-level drip instructions override this default. A single oversized rendered “S” as a solid volumetric liquid-glass sculpture, captured at the instant of mid-solidification. Clear translucent glass transitions from nearly colorless thin contours to saturated blue-cyan and teal refractive depth through the thick curved volumes. The surface is wet, mirror-glossy, and continuously rounded, with intense white specular crowns tracing every maximum-curvature bend. Fine internal caustic lattices, suspended cyan light streaks, and refracted highlights travel through the transparent body; no drips, dangling trails, or liquid runoff. Soft overhead diffused key lighting produces broad luminous reflections while a restrained cool rim light separates the glass edge from the backdrop. Background is a clean airy pastel field blending pale lavender, ice blue, and mist-white, with faint defocused caustic pools on the surface plane. Preserve generous negative space and crisp silhouette separation, emphasizing the sculptural thickness, optical distortion, and polished contours of the rendered text.
