Prompt
Aspect ratio 2:3. Minimal deep charcoal background with subtle grain and a soft vignette, keeping the upper area quiet and readable. In the lower third, slightly left of center, a zipper opening reveals a thin slice of warm amber light and a shadowy interior beyond. A small mask-like sprite peeks from inside, holding the zipper tab, with the glow catching the edges of the zipper teeth. The opening stays narrow and controlled, emphasizing minimalism and mystery. Lighting is low-key with crisp rim highlights and a restrained glow spill. Surfaces remain clean and unlettered, focusing on the seam and negative space.
