  "prompt": "A square 1024x1024 image in a painterly, slightly surreal style, reminiscent of magical realism. The central image is an antique mandolin, intricately carved, lying on a weathered, dark wooden surface. Around the mandolin, wisps of ethereal, translucent mist are gently swirling, suggesting memory and mystery. In the background, subtly blurred, are hints of a twilight sea meeting a distant, softly lit coastline, implying a sense of longing and passage of time. The color palette is dominated by deep blues, muted teals, warm ochres, and touches of antique gold, creating a mood that is both melancholic and wondrous. The lighting is soft and atmospheric, with a single, gentle light source illuminating the mandolin. The overall composition should be elegant and evocative, with a sense of depth and quiet drama, suitable for a professional audiobook cover. NO text, NO letters, NO words, NO title, NO author name.",
