Abstract blue gradient wallpaper

Create a minimalist, abstract, full-screen gradient wallpaper on a 16:9 landscape canvas. Use a smooth, soft-focus blue gamut, free of any text, objects, visible shapes, or borders. The composition should transition from a deep navy and near-black in the upper left corner to saturated cobalt and royal blue in the center, then to a brighter azure and electric blue on the right, with a subtle icy blue halo near the lower right corner. Maintain an organic feel and slight unevenness in the gradient, like a blurred, luminous surface, with a subtle diagonal movement from darker shades in the upper left to lighter shades in the lower right. Use high-resolution, clean digital rendering to reduce noise and present a refined, modern technological aesthetic. Main color scheme:{argument name="dark corner color" default="Near black navy blue"} ,{argument name="central blue" default="Deep cobalt blue"} , as well as{argument name="bright glow color" default="pale ice blue"} .
