🌉 Cable-Stay Vortex Shedding Lock-in Resonance (2D elevation)

2D elevation of a cable-stayed bridge: wind sheds vortices at the Strouhal frequency and drives each stay, which resonates when the frequency matches its string mode. Same stay-oscillator module as the 3D page, with free-decay and resonance checks.
