  "prompt": "A square, 1024x1024 professional audiobook cover image. The artwork should evoke a noir-thriller atmosphere with elements of social drama. Dominant imagery features a silhouette of a man in a trench coat and fedora, standing on a rain-slicked cobblestone street. In the background, the blurred outline of a sprawling, dimly lit city skyline with hints of art deco architecture. Subtle visual cues suggesting \"waves\" or \"frequencies\" could be incorporated abstractly, perhaps through rippling reflections in puddles or a stylized halo around a distant, glowing neon sign. The color palette is moody and desaturated, with deep blues, greys, and muted purples, punctuated by stark contrasts of light and shadow. A single, stark, cold light source illuminates the man from the side, casting long, dramatic shadows. The overall composition is dramatic and atmospheric, hinting at mystery and danger without any textual elements.",
