Abandoned Soviet-era silo schematic “forgotten in the forest”

{
  "input": {
    "prompt": " Cutaway illustration showing an underground Soviet-era missile silo beneath a pine forest: a circular concrete shaft with rusted metal ladders, collapsing support beams, water seepage and ice, and an old warhead compartment degraded by time. Above ground: innocuous trees and snow. The art should suggest decades of neglect—peeling paint, faded warning stencils in Cyrillic, and a partially caved-in access hatch hidden by drifted snow."
