  "kind": "building",
  "id": "ceramic-kiln",
  "role": "material-maker",
  "name": "Ceramic Kiln",
  "footprint": "2×1.67 tiles",
  "function": "A kiln crew fires the chalk-ceramic shells, roof blades and repair collars needed across Serravane.",
  "shape_and_silhouette": "A low brutal firing core is split by a jagged black thermal spine that rises into one hooked exhaust blade, while lateral ribs rake over the roof as broken, tapering strokes.",
  "visual_description": "Near-black heat-scarred supports and thick-to-thin fissure lines cut across rose-dark ceramic planes, concentrating at the loading mouth before shooting into sparse sharp terminals above the chimney.",
  "production_notes": "The +Z loading opening remains a clear round kiln mouth in a heavy basalt frame, a connected left-rear flue supports the hooked chimney blade, ceramic drying shelves line the right side, and rear ash access sits below the roof’s black front-to-back thermal spine.",
  "departure": "Its black lines appear burned into structure and repaired through repeated firings, giving the practical kiln a harsher scarred intensity than the other yards.",
  "shared_traits": [
    "Black structural ribs vary from heavy roots at junctions to needle-thin tips, with finer secondary filament lines.",
    "Several ribs converge into dense asymmetric knots, then splay into long crossing sweeps with sharp hooked terminals.",
    "Pale ceramic or bone-glass infill occupies isolated pockets inside a predominantly black visible skeleton."
  ],
  "constraints": [
    "Keep geometry inside the fixed 48×40 world-unit footprint with a centered +Z loading mouth.",
    "Show chimney connection, side shelves, rear hatch and a roof whose jagged black spine is visible from above.",
    "Avoid quaint masonry, decorative gothic trim and a conventional pitched-roof silhouette."
  ],
  "idle_animation": "A faint heat shimmer rises inside the chimney and a narrow ember glow waxes behind the front mouth.",
  "day_night": "The rose-clay body reads matte by day; at night only the loading mouth, chimney throat and a few cracks show low amber heat."
