    "prompt": " Photo still life in a softly lit bedroom: a sleek black/gray tDCS headband device (generic-looking, not overtly branded) resting beside a smartphone showing a treatment app home screen (neutral UI with “Session ready” and a battery icon), a USB-C charging cable plugged into a wall adapter, and a small instruction booklet. Visual tone: modern, consumer-tech aesthetic that humorously resembles a wellness gadget; keep medical vibe subtle (clean, minimalist) with no visible patient data."
