saunaRoom

Builds the sauna interior for Sauna Master out of voxel shapes: the plank-walled room with two-tier lauteet benches and a warm window, the kiuas stove (stone basin, glowing firebox, chimney), the löyly bucket with its kauha, the refill barrel, the door, and the vent flap — plus the warm lights and the steam / fire particle emitters.

M.layout exports the world-space anchor points (bench seats, kiuas, bucket, barrel, door, player spawn) that the game component uses for seating and proximity-gated interactions. M.build() is called from the scene entrypoint on every load in both modes; the entities are temporary, so nothing here bloats scene.json.
