Glassmorphism Feature Card

Create a single premium glassmorphism feature card. The card should float over a dark, saturated gradient background. Use backdrop-filter blur, a thin semi-transparent white border, and an inner radial gradient highlight near the top-left corner to simulate glass reflection. Add a slowly rotating conic-gradient glow behind the card on hover. Inside, place a sharp icon, a bold headline in white, and a short description in white/60. Use a monospaced tag/label above the headline. Typography should feel precise and high-end. Ensure the glow effect is pure CSS and does not use images. Use Tailwind CSS.

创建一个高端玻璃拟态功能卡片。卡片应悬浮在深色饱和渐变背景之上。使用 backdrop-filter 模糊、半透明白色细边框，以及左上角附近的内径向渐变高光来模拟玻璃反射。悬停时在卡片背后添加缓慢旋转的锥形渐变光晕。内部放置锐利图标、白色粗体标题和白色/60 透明度的简短描述。标题上方使用等宽标签/眉标。排版应显得精准而高级。确保光晕效果为纯 CSS，不使用图片。使用 Tailwind CSS。
