# Instantiates the contents of a PlanetSetup onto a landed surface. Capture
# points are placeholder markers here; #43 replaces them with the real
# CapturePoint scene through the same apply_setup() entry point, and enemy
# spawning is filled in by the enemy-foundation ticket (#44). Keeping this
# seam stable is the point of this ticket.
