霓虹数字 App 图标

Create a polished mobile app icon featuring a single large stylized numeral {argument name="number" default="9"} centered slightly left on a square canvas with very rounded corners. Use a deep midnight navy-to-purple background with subtle radial shading and a faint vignette. The numeral should be thick, smooth, glossy, and dimensional, like a custom sans-serif 3D glyph, with a luminous gradient running from golden yellow and orange at the upper left through hot pink in the middle to vivid violet and electric purple at the lower tip. Add a soft neon rim light and inner glow around the digit, with a stronger warm glow on the top-left edge and magenta-purple glow on the bottom curve. The right side of the numeral dissolves into a dynamic particle burst: dozens of circular dots and small speckles of varied sizes scattering outward to the right, colored orange, red, pink, magenta, and purple, densest near the digit and fading into the dark background. Keep the composition clean and iconic, with no text other than the numeral, no border, no watermark, high contrast, modern iOS-style app icon, crisp edges, vibrant gradient lighting, and a premium digital-art finish.

创建一个精致的移动端 App 图标，在带有圆角的方形画布上，居中偏左放置一个醒目的艺术化数字 {argument name="number" default="9"}。背景采用深邃的午夜蓝到紫色的渐变，辅以微妙的径向阴影和淡淡的晕影效果。数字应呈现出厚实、平滑、光亮且具有立体感的质感，类似于定制的无衬线 3D 字形；其渐变色从左上角的金黄色和橙色，过渡到中间的亮粉色，再到下端的鲜艳紫罗兰色和电光紫色。为数字添加柔和的霓虹轮廓光和内部发光效果，左上边缘带有强烈的暖色光晕，底部曲线则呈现洋红色至紫色的光晕。数字右侧消散为动态的粒子爆发效果：数十个大小不一的圆形点和微小斑点向右侧散射，颜色涵盖橙、红、粉、洋红和紫色，在靠近数字处最为密集，并逐渐淡入深色背景中。保持构图简洁且具有标志性，除数字外不含任何文字，无边框，无水印，高对比度，现代 iOS 风格 App 图标，边缘清晰，渐变光影鲜明，呈现高级数字艺术质感。
