Wide desktop wallpaper on a deep navy-black field with expansive negative space. An off-center mass of soft glow shapes sweeps diagonally across the frame, leaving a calm void on one side. Small luminous gradient forms echo into the opposite corner for balance and slight chaos. Magenta spill blends into cyan and teal halos with gentle bloom and thin haze. Bright glow values stand against near-black shadows for crisp separation in a cinematic digital render with subtle film grain.
