  "prompt": "A minimalist, abstract digital painting for a book cover. The dominant visual element is a swirling, ethereal vortex of soft, muted blues and deep indigos, subtly transitioning into warm, dusky oranges and pale, faded lavenders at the periphery. Within the vortex, faint, almost imperceptible lines suggest movement and flux, like the trailing wisps of smoke or subtle currents in water. The overall mood is contemplative, serene yet tinged with a sense of gentle melancholy and introspection. The composition should be centered, with a sense of depth and quietude. The texture should be smooth and blended, creating a dreamlike atmosphere. Professional audiobook cover aesthetic, square 1024x1024 format. NO text, NO letters, NO words, NO title, NO author name.",
