黑缎与金箔向上翻涌的暗场

Intended use: a mobile backdrop with a mysterious, elegant mood, suited to premium phone screens. Keep a tall vertical band of negative space inside the shadows, clear for light-colored text. Render: 3D cloth simulation, vertical 2:3 composition. Metallic gold fabric and black satin wind around one another and rise through a dark void. The lighting is low-key and dramatic, skimming the fold edges to produce sharp golden highlights against deep black shadows. A high specular sheen makes the cloth look like heavy, expensive satin.

竖幅 2:3 构图，3D 布料模拟渲染。黑色缎面与金属金色织物相互缠绕，在暗色虚空中向上流动。低调戏剧性布光擦过褶皱边缘，在深黑阴影中切出锐利的金色高光，强烈的镜面光泽读作厚重昂贵的缎面。在阴影里保留一大块竖向负空间，留给浅色文字。整体神秘优雅，专为高端手机壁纸设计。
