  "kind": "building",
  "id": "sunpetal-collector",
  "role": "sunshine-harvester",
  "name": "Sunpetal Collector",
  "footprint": "2.25×1.65 tiles",
  "function": "A one-worker weather instrument folds radiance from nearby sunfields into portable stores of sunshine.",
  "shape_and_silhouette": "A squat cloudstone service core supports a high fan of five broad heliostat petals, producing a bright stepped silhouette that leans toward the sun while leaving the front entrance visible below.",
  "visual_description": "Amber glass petals sit in simple copper ribs above a flat blue-grey maintenance roof, a deep +Z oval door opens through the thick front wall, narrow rear vents reveal the pumice frame, and a splayed grafted platform braces the collector arm from both side elevations.",
  "production_notes": "This is a recent but optimistic weather-working type placed on open sunward shelves, built more precisely than a house but still carrying hand-set copper shoes and visible glass repairs.",
  "departure": "It turns the domestic Sunpetal Oriel into a freestanding working crown whose luminous fan dominates an otherwise blunt utility base.",
  "shared_traits": [
    "Wind-rounded cloudstone masonry around a buoyant pumice frame.",
    "Copper fittings, vapour rope, and visible bands of repaired prism glass.",
    "Deep openings and a stable silhouette shaped for exposed cloud shelves."
  ],
  "constraints": [
    "The main entrance faces +Z and remains readable beneath the petal assembly.",
    "Resolve the petal backs, collector hub, rear vents, side braces, and platform underside.",
    "Build each petal as a rigid framed panel with simple hinges rather than a sculpted organic surface."
  ],
  "idle_animation": "The five heliostat petals make slow, shallow tracking adjustments in unison around the fixed collector hub.",
  "day_night": "In daylight the petals burn Sunwell gold, while after dusk they fold slightly inward and retain a dim amber afterglow along their copper ribs."
