🪀 Spinning Top — 2D Precession, Nutation and Axis-Tip Trace

2D companion of the spinning top: Lagrange-top equations of motion with the axis-tip trace on the unit sphere, tilt angle and precession-rate plots, spin-decay wobble and the sleeping-top stability threshold, with in-page checks against closed-form precession and nutation.
