  "prompt": "A minimalist, high-contrast square illustration, 1024x1024. The central image is a single, imposing, dark grey, rough-hewn stone boulder, seemingly mid-roll down a steep, barren, earthy-brown slope. The slope is rendered with subtle, abstract textural lines suggesting both rock and dried earth. Above the boulder, in the upper third of the image, a stark, pale, almost white sky dominates, with a hint of diffused, soft sunlight breaking through from a high, unseen source, casting faint, elongated shadows. The overall mood is somber, existential, and solitary, with a powerful sense of relentless motion and struggle. The color palette is deliberately restrained: deep earthy browns, charcoal greys, and a very pale, luminous white for the sky. The composition emphasizes the scale and isolation of the boulder against the vastness of the sky and the unforgiving terrain. Professional audiobook cover aesthetic, square 1024x1024 format, no text.",
