🌍 Precision Seismic Isolation Platform — 2D Multi-Stage Transmissibility

2D companion of the seismic isolation platform: a chain of one to three damped spring-mass stages driven by ground motion, time-domain response, transmissibility in dB against frequency, resonance peak and the high-frequency roll-off, checked against the closed-form and complex-matrix results.
