Right - anyone who deals with chiral spaces learns whatever convention is used
for that system.

There is a "Right-hand rule" for physics (electromagnetism), engineering, math,
architecture, etc.

The left hand rule for POV-ray ought to be just as straightforward.

*** Point the left thumb in the +axis direction, curl the fingers, and that's
the positive direction of rotation.   ***

A picture or two may be a nice addition, but I don't think anything needs to be
added to the text or changed.
