  "concept": "Reef Tender: a communal maintenance diver carrying a miniature living coral nursery on its back.",
  "silhouette": "Squat shell-suited swimmer with an oversized octagonal helmet, broad shoulders, short arms and two wide paddle fins; a chunky nursery pack distinguishes the rear.",
  "details": "Dark inset visor with two cyan eye slits, bronze helmet collar, coral sprigs above the backpack, a simple gripping mitten and a short cultivation tool.",
  "value": "Nursery load from 0 to 1 raises three carried coral plugs and brightens the pack status lamps; locomotion remains controlled solely by travelSpeed.",
  "animation": "Stationary buoyant hover; increasing travelSpeed pitches the body toward a nearly horizontal swim (about 69 degrees at 0.5 u/s, 79 at 1), with alternating fin kicks and a counter-tilted helmet that looks forward; load stays independent.",
  "variation": "Three distinct silhouettes: broad keeper with brow and twin canisters, tall scout with beacon and long fins, compact gardener with crest and fork; seeded shell colors, coral height, body breadth and tool side add independent differences.",
  "colors": "Barnacle-white shell plates over a deep-teal undersuit, oxidized bronze joints, near-black visor, cyan eye and pack lamps, sea-green or yellow-green coral."
