Submarine as motivational exhibit: “You don’t have to go down there”

{
  "input": {
    "prompt": " Museum-style photo/illustration of a small submarine on display indoors with velvet ropes and an information placard that reads “REMEMBER: YOU DO NOT HAVE TO GO DOWN THERE.” A family looks at it the way people look at a haunted artifact. Lighting is gentle and reassuring; a gift shop corner sells postcards of “Nice Water.”"
