  "kind": "building",
  "id": "graft-workshop",
  "role": "fabricator",
  "name": "Graft Workshop",
  "footprint": "2.5×2 tiles",
  "function": "Artisans combine living fiber, shell ceramic and brine into finished conductive grafts for repairs and new construction.",
  "shape_and_silhouette": "A tall black fabrication knot splits into a low open testing wing and a higher enclosed making wing, with roof ribs crossing at violent angles before thinning into long sideward hooks.",
  "visual_description": "Dense black braces, overlapping sigil sweeps and sharply tapered test arms nearly overwhelm the pale ceramic infill, while tiny exposed clamps and glass inspection slits reveal precision inside the aggressive exterior.",
  "production_notes": "A central +Z entrance separates the two unequal bays, heavy basalt uprights carry extruded black roof ribs, the right testing colonnade remains open, the left bay retains high work windows, and a supported rear loft stores ceramic and graft stock.",
  "departure": "The workshop makes complex splices and crossings its visible craft, turning the building into a large three-dimensional diagram of joining and tension.",
  "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 60×48 world-unit footprint and put the main entry at center +Z.",
    "Expose the rear loft, side bays and physical attachment of every major black arm from all views.",
    "Avoid a cozy artisan workshop, folded petal roof and fine black decoration confined to white walls."
  ],
  "idle_animation": "One restrained teal impulse follows a test strand from its ceramic clamp to a small terminal bud before fading.",
  "day_night": "Day shows the workshop's contrasting closed and open bays; at night warm work light glows behind the high windows while the test rig briefly flashes cold teal."
