钟表匠桌上的黄铜小龙

Photorealistic macro scene of a palm-sized mechanical dragon resting on a cluttered old watchmaker's workbench. Its body is built from aged brass and blued steel, with exposed gear trains in the chest, riveted wing membranes of thin copper sheet, and one wing folded open to show fine linkages. A jeweler's loupe, tweezers, tiny screws and a coil of spring lie around it. Warm task lamp from the left, soft dark background, shallow depth of field with focus on the head and one glowing amber glass eye, worn patina and fingerprints on the metal. No text, no logos, no people.

写实微距场景：一只巴掌大的机械龙卧在杂乱的老钟表匠工作台上。龙身由旧黄铜和烧蓝钢组成，胸口露出齿轮组，翅膜是铆接的薄铜片，一侧翅膀张开露出精细连杆。周围放着放大镜、镊子、细螺丝和一卷发条。左侧暖色台灯，背景柔暗，浅景深，焦点落在头部和一只发光的琥珀玻璃眼上，金属有包浆和指纹。没有文字、标志和人物。
