  "input": {
    "prompt": " Minimalist illustration or photo-styled graphic: a beige room with a plain wall, a small pile of pebbles on a windowsill, a paper wall calendar on the wall, a generic refrigerator slightly off to the side with subtle “hummm” vibration lines, and an average cloud seen through the window. The scene should feel intentionally bland but aesthetically pleasing—“Switzerland of existence.”"
