這個夜藍約等於隱藏款質感
石板灰背景壓著一圈鳥頭暗紋，細節全靠倒角和一圈極淡的內發光撐起來。
✍️ 整張圖撐住質感的其實是那圈"很淡的內發光"——發光太強就顯廉價，太弱又看不出輪廓，這個分寸才是稀有款和普貨的差距。

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.

畫幅比例為3:2，極簡的午夜石板灰背景帶有細膩顆粒感，左側保留大片負空間。在右三分之一處，一處倒角暗示出一層淺淺的凹陷，凹陷之後隱約浮現出一個鳥頭的輪廓剪影，邊緣勾著一圈極淡的內發光。剪影保持抽象且質感高階，對比可控、邊緣乾淨。光線整體偏低沉，只在倒角處留下細細的輪廓高光，發光外溢極少。整體構圖保持簡潔沉靜，所有表面乾淨、不帶任何文字。
