Simulation Details
Two point masses (equal mass) connected by massless rigid rods (equal length).
Gravity: 9.81 m/s² downward.
Initial angles: θ₁ = 120°, θ₂ = -10° (measured from downward vertical).
Initial angular velocities: zero.
Integration: 4th-order Runge-Kutta (RK4) with fixed time step.
The lower bob leaves a fading colorful trail (last 300 positions).
Pause/Resume toggles simulation; Reset restores initial state and clears trail.
