Minimalist Embossed Paper Eastern Commemorative Key Visual

Full prompt

Square minimalist commemorative poster in a 1:1 aspect ratio, set against a warm white embossed paper background with over sixty percent clean negative space. At the center stands a vertical crimson capsule-shaped art installation, surrounded by colorless blind-debossed fine line art depicting rolling mountains, rivers, soaring birds, ancient city walls, aeronautical flight trajectories, and subtle mechanical gear patterns. Soft directional side lighting accentuates the tactile relief and fibrous texture of the debossed paper, balanced in a refined two-tone red and white palette with modern Eastern elegance, restrained composition with empty space reserved for bottom-center typography, rendered clean with no text, no characters, no watermark, no QR code, and no logo.
