  "prompt": "A minimalist, atmospheric audiobook cover. The main imagery should evoke the feeling of fragmented communication and underlying emotional turmoil. Imagine a slightly out-of-focus, vintage black and white photograph of a single, old-fashioned rotary telephone handset lying on a dark, textured surface like worn wood or aged paper. The handset should be positioned slightly off-center, with its cord trailing loosely. Subtle, almost imperceptible light rays should emanate from the earpiece, suggesting a faint, distant voice or a lingering thought. The overall mood should be melancholic, introspective, and subtly unsettling, with a color palette dominated by deep blacks, muted grays, and a hint of sepia or desaturated blue. The composition should feel intimate and slightly claustrophobic, emphasizing the isolation of the subject. The aesthetic should be professional and sophisticated, suitable for a literary audiobook cover. Square 1024x1024 format. NO text, NO letters, NO words, NO title, NO author name — only visual artwork.",
