这个夜蓝约等于隐藏款质感
石板灰背景压着一圈鸟头暗纹，细节全靠倒角和一圈极淡的内发光撑起来。
✍️ 整张图撑住质感的其实是那圈"很淡的内发光"——发光太强就显廉价，太弱又看不出轮廓，这个分寸才是稀有款和普货的差距。

Set at a 3:2 aspect ratio, a minimal midnight-slate backdrop carries subtle grain while leaving broad negative space across the left side. Toward the right third, a hint of bevel implies a shallow recess, and behind that surface a faintly outlined silhouette of a bird's head appears, traced with a very subtle inner glow. Keep the silhouette abstract and premium-looking, its contrast controlled and its edges clean. Lighting stays moody, laying thin rim highlights along the bevel with only minimal glow spill. The overall composition remains uncluttered and calm, every surface left clean and unlettered.

画幅比例为3:2，极简的午夜石板灰背景带有细腻颗粒感，左侧保留大片负空间。在右三分之一处，一处倒角暗示出一层浅浅的凹陷，凹陷之后隐约浮现出一个鸟头的轮廓剪影，边缘勾着一圈极淡的内发光。剪影保持抽象且质感高级，对比可控、边缘干净。光线整体偏低沉，只在倒角处留下细细的轮廓高光，发光外溢极少。整体构图保持简洁沉静，所有表面干净、不带任何文字。
