Replace every placeholder-cube ghost prefab with nested Synty (PolygonFantasyKingdom) models: ResourceNode->crystal, Turret->ballista, Wall->spike palisade, Pylon->crystal beacon, Storage->chest, UpgradePickup->gem, BlightClutter->rock chunk (nest as a Model child, strip colliders, reset the [GhostField] root Scale, atlas for bare FBXs). Gameplay subscene: place the BaseFieldSpawner, trim Harvester/Fabricator/Conveyor from the build palette. CycleDirector prefab bakes the schedule siege config. See DR-031.
