Aspect ratio 2:3. Minimal near-black background with subtle grain and a soft vignette, keeping the upper area quiet and readable. In the lower third, slightly left of center, a rounded capsule window reveals a dark aquarium with faint bioluminescent algae and a few slow bubbles. A small 3D deep-sea fish mascot appears near the window, lit by a tiny cool glow that fades into the dark water. The glass shows subtle moisture and a thin highlight rim, keeping the effect premium and restrained. Lighting is low-key with controlled glow inside the window. Surfaces remain clean and unlettered, focusing on mood and minimalism.
