纯黑虚空中的液态银光流体

将一只极简香水瓶小巧地居中悬浮于纯黑虚空（#000000）中，主体占画布不超过50%，且完整呈现、不被裁切。让产品整体轮廓化为向下流淌的光滑液态金属垂直流线，如水银或熔融银液。流线柔滑、流体感强、自然有机且彼此柔和融合，粗细与亮度富于变化，带有发光渐变、冷色单色蓝银虹彩、明亮镜面高光和深邃阴影。效果控制在产品整体轮廓范围内，四周留出充足黑色负空间。不要硬边、尖角、僵硬杆状物、块状板条、镀铬块、几何圆环、水平线、暖色、彩色背景、平淡照明、哑光表面或可读文字。画面比例为4:5。

【English Prompt】
Visualize a minimalist perfume bottle floating small and centered against a pure black void (#000000), occupying no more than 50% of the canvas and never cropped. Dissolve the product's general silhouette into smooth vertical liquid-metal streaks that flow downward like mercury or molten silver. Make the streaks buttery, fluid, organic, and softly blended, with varied thickness and luminosity, luminous gradients, cool monochromatic blue-silver iridescence, bright specular highlights, and deep shadows. Keep the effect contained within the product silhouette with generous black negative space around it. No hard edges, sharp corners, rigid bars, blocky slats, chrome blocks, geometric rings, horizontal lines, warm colors, colored background, flat lighting, matte finish, or readable text. Use 4:5.
