    "Office, retail, and factory generation, export, and loading scenes into Nebula are excluded."

  "acceptance_outcomes": [
    "The service rejects empty, too-short, or oversized briefs before generation.",

    "Furniture reflects room purpose and available space.",
    "Ambient, sunlight, and room lighting complete the scene.",
