抽象蓝色渐变壁纸

Create a simple abstract full-frame gradient wallpaper in a 16:9 landscape canvas. Use a smooth, soft-focus blue color field with no text, no objects, no visible shapes, and no borders. The composition should transition from very dark navy and near-black in the upper-left corner into saturated cobalt and royal blue across the center, then into brighter azure and electric blue toward the right side, with a pale icy blue glow near the lower-right area. Keep the gradient organic and slightly uneven, like a blurred luminous surface, with subtle diagonal movement from dark upper left to bright lower right. Use high resolution, clean digital rendering, minimal noise, and a polished modern tech aesthetic. Main palette: {argument name="dark corner color" default="near-black navy"}, {argument name="central blue" default="deep cobalt blue"}, and {argument name="bright glow color" default="pale icy azure"}.

创建一个 16:9 横向画布的简约抽象全屏渐变壁纸。使用平滑、柔焦的蓝色色域，不包含任何文字、物体、可见形状或边框。构图应从左上角的深海军蓝和近黑色，过渡到中心区域的饱和钴蓝和宝蓝色，再向右侧过渡为更明亮的蔚蓝和电光蓝，并在右下角附近呈现淡淡的冰蓝色光晕。保持渐变的有机感和轻微的不均匀感，如同模糊的发光表面，并带有从左上角深色到右下角亮色的微妙对角线动感。使用高分辨率、干净的数字渲染，减少噪点，呈现精致的现代科技美学。主色调：{argument name="dark corner color" default="近黑色海军蓝"}, {argument name="central blue" default="深钴蓝色"}, 以及 {argument name="bright glow color" default="淡冰蔚蓝色"}。
