Behind the pipe organ: the too-small hiding cavity

{
  "input": {
    "prompt": " Photo inside an old stone church showing the side/back of a large pipe organ with a maintenance panel open. A narrow cavity is visible with dust, cobwebs, and a tucked bundle of aged parchment fragments wrapped in cloth. Include a technician’s gloved hand holding a flashlight, emphasizing scale (“too small for treasure”). Warm, moody interior light with strong contrast."
