/**
 * A Tender with its headlight on, a couple of dim fill lights and a seabed to catch the beam, for looking at the model. It is not
 * part of the map (the map holds only a PlayerStart, everything else is spawned by code): the `kazah_showcase` and `kazah_closeups`
 * scenarios spawn it with FindOrSpawn. It has no fog or exposure of its own since the integration pass: ADescentEnvironment is the
 * only authority for those. Everything is relative to the actor. The fill lights are in the game's unitless light units.
