const ORBIT_LENGTHS: Readonly<{ max: 8; min: 0.6 }>
How far the orbit may stand from the hull, in hull lengths.
The near bound is the chase offset's own reach, so an orbit never dollies
inside the hull it is looking at; the far bound is a tether, and it is a
design rule rather than a limit of the arithmetic: docs/design/art.md
bounds the free camera to a tether from the ship so that the camera stays
a drone the player deployed rather than a second viewpoint on the
universe. Eight lengths is where the hull is still the subject of the frame
at the default lens.
