发光 3D 心跳 App 图标

Create a clean 3D app-icon style hero image on a wide 16:9 canvas. Center a single floating rounded-square icon with glossy beveled edges, colored {argument name="icon color" default="electric violet blue"}, with a subtle translucent rim, soft inner highlights, and four tiny circular screw-like dots near the rounded corners. On the face of the icon place a raised glowing white heartbeat waveform symbol, thick and smooth, casting a gentle shadow on the icon surface. The icon should hover slightly above the background with a soft purple glow and drop shadow. Use a dark cinematic abstract background: nearly black at the top fading into deep purple and magenta, with blurred neon blue-violet wave shapes along the bottom edge and a faint central haze. Lighting should feel premium, futuristic, minimal, and polished, with no text, no people, no extra objects, and generous negative space around the centered icon.

在 16:9 的宽画布上创作一张简洁的 3D App 图标风格首屏图像。在中心放置一个悬浮的圆角方形图标，边缘带有光泽的斜面，颜色为 {argument name="icon color" default="电光紫罗兰蓝"}，带有微妙的半透明边框、柔和的内部高光，以及靠近圆角的四个微小圆形螺丝状点。在图标正面放置一个凸起的发光白色心跳波形符号，线条粗壮平滑，在图标表面投下柔和的阴影。图标应略微悬浮于背景之上，带有柔和的紫色光晕和投影。使用深色电影感抽象背景：顶部接近黑色，向下渐变为深紫色和洋红色，底部边缘带有模糊的霓虹蓝紫色波浪形状和淡淡的中心雾气。灯光效果应呈现出高级、未来感、极简且精致的质感，画面中不包含文字、人物或额外物体，中心图标周围留有充足的留白。
