  "cover_prompt": "A grand piano submerged halfway in still, dark water, its lacquered surface reflecting shattered golden light from an unseen source above. The surrounding atmosphere dissolves between deep indigo shadow and warm amber luminescence, evoking tension between restraint and release. Textures of cracked glass and liquid mercury blend across the surface, suggesting fragility and volatile beauty. Cinematic fine art photography with long exposure light painting.",
