Gyre Reliquary

A self-contained three-dimensional gyroscopic precession puzzle. One raycast brass torque star moves across a physical glass plate. Its actual position follows the pointer through a spring, twists two visible torque rods and applies a force to a spinning glass-and-brass rotor. The rotor axis does not chase the finger: its change is perpendicular to the applied pull and inversely scaled by remaining spin. Return the star toward center to damp the axis inside four numbered world-space halos before the rotor expires or the axis strikes an ash bearing.
