Aspect ratio 3:2. Minimal midnight slate background with fine grain and a subtle gradient, preserving broad negative space on the left side. On the right third, a recessed cutout window shows tiny 3D workers adjusting a small warm light inside the cavity, illuminating only a small area. The inner light creates a soft glow spill on the cavity walls, while the outer surface remains dark and matte. Props are minimal and neatly arranged to avoid clutter. Lighting is low-key with controlled rim highlights. Surfaces remain clean and unlettered, emphasizing mood and negative space.
