A sleek and minimalist professional book cover design for an audiobook, atmospheric noir style, a stylized silhouette of a graceful cat lurking in the shadows of a grand, dimly lit Victorian library, soft moonlight filtering through a tall arched window creating dramatic contrast, deep charcoal and midnight blue color palette with hints of gold dust, the aesthetic is sophisticated and enigmatic, clean composition, high-end digital art style, cinematic lighting, hyper-realistic textures, no text, no letters, no words, no title, no author name, square 1024x1024.
