创建一个由真实机械键盘键帽完全构成的逼真 8K 俯视平铺构图，描绘一只狗。键帽应为 OEM 或 Cherry 高度、哑光 PBT 塑料材质，并以紧密、均匀的网格排列。每个键帽都必须包含清晰、逼真的字符——字母、数字、标点符号、功能键、箭头和符号——采用双色注塑或热升华工艺印制。不允许出现空白键帽。字符的分布应感觉自然随机，如同来自真实的键盘，并具有可信的变化。 键帽必须精确排列，以形成清晰、易于识别的狗的侧面轮廓。轮廓应锐利分明，具有平滑的轮廓过渡，准确捕捉狗的头部、耳朵、身体、腿和尾巴。轮廓之外应是纯白色的负空间，没有额外的物体或干扰。 背景必须是无缝的纯白色。构图应为 16:9 的宽高比，并完美居中。相机角度必须是精确的 90 度俯视，透视畸变最小，保持完全平坦的表面外观。 灯光应为柔和、漫射的影棚灯光，每个键帽下方有非常轻微的接触阴影，以及微妙的边缘高光，以突出塑料的纹理。避免刺眼的阴影或戏剧性的对比。整体效果应超锐利、干净、无噪点且高度细节化，展现逼真的材质纹理和精确的排列。
Create a photorealistic 8K top-down flat lay composition of a dog formed entirely from real mechanical keyboard keycaps. The keycaps should be matte PBT plastic in OEM or Cherry profile, arranged in a tight, uniform grid. Every keycap must include crisp, realistic legends—letters, numbers, punctuation, function keys, arrows, and symbols—printed in double-shot or dye-sublimated style. No blank keycaps are allowed. The distribution of legends should feel naturally randomized, as if sourced from real keyboards, with believable variation. The keycaps must be precisely arranged to form a clean, clearly recognizable side-profile silhouette of a dog. The silhouette should be sharp and well-defined, with smooth contour transitions that accurately capture the dog’s head, ears, body, legs, and tail. Outside the silhouette, there should be pure white negative space with no additional objects or distractions. The background must be seamless, pure white. The composition should have a 16:9 aspect ratio and be perfectly centered in frame. The camera angle must be an exact 90-degree overhead view with minimal perspective distortion, maintaining a completely flat surface appearance. Lighting should be soft, diffused studio lighting with very gentle contact shadows beneath each keycap and subtle edge highlights that emphasize the plastic texture. Avoid harsh shadows or dramatic contrast. The overall result should feel ultra-sharp, clean, noise-free, and highly detailed, showcasing realistic material texture and precise arrangement.
