  "role": "monumental",
  "name": "Recursive Concord",
  "function": "A civic monument preserves shared knowledge in elevated archive chambers and marks collective harmonic observances.",
  "shape_and_silhouette": "A tall faceted trunk divides into two great arms and then four smaller branches, holding four prismatic archive crowns above a pierced square pedestal.",
  "visual_description": "Continuous white crystal joints carry violet glazed crowns over a black stone base, with hairline gold inlays, luminous branching gaps, and descending square-ended chimes beneath the terraces.",
  "production_notes": "A prestigious institutional growth on an open flat court uses slow-grown crystal joints and precise conductive inlays, remaining visually separate from nearby low domestic blocks.",
  "departure": "Two successive forks are oriented in perpendicular vertical planes, giving the monument a spatial crown with distinct front and side silhouettes.",
  "shared_traits": [
    "Two visible generations of L-system branching",
    "Violet mineral infill and interior cyan light",
    "Selective gold at difficult joints",
    "Negative space between solid crystalline members"
  ],
  "constraints": [
    "Four supported archive prisms, no floating parts",
    "First fork spreads left-right; second forks spread front-back",
    "Avoid organic twisting and freeform surfaces",
    "Gold is thin inlay rather than broad cladding"
  ],
  "idle_animation": "Three short chime groups sway by only a few degrees beneath the lower terraces while a faint light sequence travels upward through the fixed branches.",
  "day_night": "Day reveals the white faceted joints and fine iridescent inlays; night strengthens cyan light within branching gaps and gives each violet crown a quiet white core.",
