Rotating Habitat Walking Gravity (2D)

A spinning ring habitat substitutes centripetal acceleration for gravity — but that substitute gravity isn't fixed the moment you start moving. This 2D cross-section companion lets you design the ring (radius and spin rate) and then walk along its rim, showing in real time how prograde or retrograde walking raises or lowers your apparent weight through Coriolis coupling with the rotating frame, how a smaller radius produces a steeper head-to-foot gravity gradient, and where your design sits on the classic radius-vs-spin-rate human-comfort envelope used in space-habitat engineering.
