🌍 Seismic Isolation Platform — 2D Transmissibility and Resonance

2D companion of the seismic isolation platform: a base-excited mass-spring-damper integrated with RK4, a live time history of ground and platform motion, and the transmissibility curve T(r) with the measured amplitude ratio checked against the analytic formula.
