  "role": "resource-collector",
  "name": "The Blackwater Harp",
  "function": "A geothermal collector captures vent heat and dissolved minerals through a serviceable bank of intake bells and condenser tubes.",
  "shape_and_silhouette": "Five towering backward-curved hollow tusks rise in an ascending fan from a low horseshoe of pressure vessels, with thin vertical condenser tubes stretched inside each tusk like the strings of a colossal harp.",
  "visual_description": "Black ceramic blades, verdigris bronze plumbing and patchwork white vessel jackets turn marine engineering into a skeletal silhouette, punctuated by tiny yellow service marks.",
  "production_notes": "Working-district vent engineering taken to a vertical extreme, on a flat anchored platform surrounding a low collector inlet rather than perched on a vent chimney.",
  "departure": "Replace the city\u2019s usual swollen pale masses with a porous black fan whose negative spaces dominate its silhouette.",
  "shared_traits": [
    "Replaceable ceramic jackets",
    "Exposed oxidized bronze service frames",
    "Yellow machinery markers"
  ],
  "constraints": [
    "Exactly five curved hollow tusks",
    "Condenser tubes are rigid plumbing, not cables or musical strings",
    "No coral on hot equipment",
    "No unsupported suspended machinery"
  ],
  "idle_animation": "Small bubble trains escape two outlet nozzles and indicator lights pulse slowly; the tusks and condenser tubes remain fixed.",
  "day_night": "No solar response; cyan mineral-flow indicators persist while yellow maintenance markers remain constant.",
