An entire cave worth of question marks beneath the base (“The Beneath Question”)

  "input": {
    "prompt": " Cutaway/diagram-style illustration: on the surface, a cozy base; beneath it, an underground cavern filled with dozens of question marks carved into walls and freestanding pillars—varied sizes, made from different stone types, arranged like an eerie gallery. Include torches placed by the homeowner in a defensive pattern, and a vertical “test shaft” where the player has dug down to discover the chamber. Lighting should be torchlit, with deep shadows to feel unsettling rather than dangerous."
