🚀 Booster Touchdown on a Heaving Ocean Platform: Wave Heave, Leg Crush and Tip-Over Limits

Land a generic reusable rocket booster on a rolling ocean platform: choose the ignition height and throttle (or let guidance help), fight a 40 % throttle floor that rules out hovering, wind and a deck that heaves up to 2.4 m, and see touchdown speed, tilt, leg-crush stroke and tip-over margin against the 2 m/s and 5 degree limits. Includes a sea-state experiment and a check of the closed-form burn height against the integrated trajectory.
