Aspect ratio 2:3. Minimal near-black background with subtle grain and a soft vignette, keeping the upper area calm and empty. In the lower third, slightly left of center, a cutout seam opens to reveal a deep inky liquid with a faint neon rim, pooling behind the surface. A small 3D shadow blob mascot braces against the edge from inside, with two dim glowing eyes and a soft matte body. The liquid shows glossy highlights and a few suspended droplets that catch the light. Lighting is low-key with a cool highlight sweep and a subtle inner glow around the seam. Surfaces remain clean and unlettered, emphasizing contrast and restraint.
