🪢 Capstan Rope Friction and Holding Force (2D top view)

Top view of a rope wrapped around a rotating drum: tension grows as exp(mu theta) along the wrap, so a small tail pull holds a large load until the wrap runs out and the rope slips. Same Euler-Eytelwein law as the 3D page, with ODE, torque and doubling-turn checks.
