  "input": {
    "prompt": " Photo of an adult sitting on a couch in a modest living room, wearing a tDCS headset with two front electrodes contacting the forehead and a strap around the head; a smartphone in hand displays a guided session timer/progress bar. Expression is calm/neutral, not exaggerated; lighting natural daylight. Include small details that sell “real life”—a throw blanket, a mug, and a slightly messy coffee table—without stereotyping depression."
