  "prompt": "A dark, atmospheric, square 1024x1024 illustration suitable for a historical romance or gothic novel audiobook cover. The scene depicts a dimly lit, ancient stone castle courtyard at dusk. In the foreground, a solitary, elegantly dressed woman in a flowing, deep crimson gown stands with her back to the viewer, gazing towards a grand, arched stone doorway that leads into the castle's interior. Moonlight filters through a sliver of cloud, casting long, dramatic shadows across the cobblestone ground. Gnarled, ancient ivy climbs the castle walls, and a single, wrought-iron lantern hangs precariously, its faint glow illuminating a small patch of the worn stones. The overall mood is one of mystery, foreboding, and a touch of melancholic beauty. The color palette is dominated by deep indigos, muted greys, rich crimson, and accents of pale moonlight. The composition is dramatic and focused, with a shallow depth of field emphasizing the woman and the doorway. Professional, painterly digital art style, evoking old master paintings with a hint of romanticism. No text, no logos.",
