Create a wide, calming background with a deep navy base—smooth, matte, and noise-textured. In the center, add a soft, flowing wave of light made from layered gradients: cool tones like icy blue, violet, and soft lavender. Let the light gently fade into the background, forming a peaceful curve that stretches horizontally like a breeze. The glow should be diffused, almost foggy, with no sharp edges—just smooth transitions and airy motion. Keep the scene ultra-clean and minimal—no extra elements, no distractions—just a serene, abstract light flow resting in a dark, spacious void.
