Glowing 3D Heartbeat App Icon

Create a minimalist 3D app icon-style homepage image on a 16:9 wide canvas. Place a floating rounded square icon in the center with glossy beveled edges and a color of [color missing].{argument name="icon color" default="Electric Violet Blue"} The icon features a subtle, semi-transparent border, soft internal highlights, and four tiny, rounded, screw-like dots near the rounded corners. A raised, glowing white heartbeat waveform symbol with thick, smooth lines is placed on the front of the icon, casting a soft shadow on its surface. The icon should float slightly above the background, with a soft purple halo and projection. Use a dark, cinematic abstract background: close to black at the top, fading to deep purple and magenta downwards, with a blurred neon blue-purple wave shape at the bottom edge and a faint central haze. The lighting effects should convey a sophisticated, futuristic, minimalist, and refined feel, without text, people, or extraneous objects, and with ample white space around the central icon.
