  "prompt": "A vintage, painterly illustration evoking early 20th-century French art nouveau. The central image is a solitary, elegant woman in a flowing, deep emerald green dress, her back partially turned, gazing out a tall, arched window. The window overlooks a misty, atmospheric Parisian cityscape at twilight, with soft, diffused light filtering through the fog and casting long, subtle shadows. Subtle hints of opulent interior decor are visible in the foreground, perhaps a glimpse of a gilded frame or velvet drapery. The overall mood is one of quiet contemplation, a touch of melancholy, and refined elegance. Color palette: deep jewel tones (emerald green, sapphire blue, amethyst purple) contrasted with soft grays, muted golds, and hints of ivory. Composition is balanced with a strong focal point on the woman and the window. Square 1024x1024 format. Professional audiobook cover aesthetic.",
