Ultra-Minimalist Abstract Nebula Background for Tech Websites

An ultra-minimalist abstract background for a tech website hero section. On a solid charcoal black background (#F8F8F9), a large, soft, ethereal glowing nebula or aurora. The light is a smooth, vibrant gradient starting from sky blue (#52AEF7), transitioning through a bright magenta (#C5399B), to a fiery red-orange (#FD4434). Heavy gaussian blur, dreamlike quality, no sharp edges, cinematic lighting.
