  "prompt": "A square, 1024x1024 image for an audiobook cover. The style should be sophisticated and slightly abstract, evoking a sense of intellectual journey and European culture. The central imagery features a partially visible, weathered stone archway, suggesting passage and historical depth. Through the arch, a blurred, soft-focus landscape of rolling hills under a twilight sky is visible. The dominant colors are muted blues, deep greys, and hints of warm, fading ochre, creating a contemplative and slightly melancholic mood. The lighting is soft and diffused, casting gentle shadows.

The aesthetic should be professional and artistic, suitable for a high-quality audiobook. No text or logos should be present.",
