미니멀 대각선 블루 그라데이션 배경화면

A simple abstract full-frame gradient wallpaper. A smooth, soft-focus blue color field with no text, no objects, no visible hard shapes, and no borders. The composition transitions from [near-black navy] in the upper-left corner into [deep cobalt blue] across the center, shifting into brighter azure and electric blue toward the right, with a [pale icy azure] glow near the lower-right area. Organic and subtly uneven blending resembles a blurred luminous surface, with subtle diagonal flow from dark top-left to radiant bottom-right. Clean digital rendering, minimal noise, sleek modern tech aesthetic.
