Prompt
Aspect ratio 2:3. Minimal charcoal background with fine grain and a soft vignette, keeping the upper area quiet and readable. In the lower third, slightly left of center, a recessed cutout window reveals tiny 3D workers installing a small glowing panel inside the cavity. The inner cavity has a subtle warm light source, while the outer surface stays matte and dark. Props are minimal: one tiny ladder, one tool case, and a single work light. Lighting is moody but clean, emphasizing depth and miniature scale. Surfaces remain clean and unlettered, focusing on restraint and story.
