Prompt

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 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.
