棱柱形玻璃图标：进阶诠释

Create a high-resolution illustration of a [skull] icon in the style of a glossy, translucent sculpture. The icon should appear as if made of curved, flowing glass with reflective surfaces. Infuse the form with vivid, refracted rainbow gradients that shift smoothly across its contours. The shape should be abstract yet recognizable, with a sleek, high-gloss finish and soft reflections that mimic light bending through clear material. Center the icon on a solid black background. No shadows, textures, or extra elements. Square aspect ratio.。变体建议：把同一构图改成插画风用作 social 卡片图，电商详情页用写实版。
