🧲 3D Magnetosphere Simulator — 2D Charged-Particle Deflection Map

2D companion of the magnetosphere simulator: an equatorial charged-particle beam in a dipole field with the Stormer forbidden region, magnetopause standoff from pressure balance, live closest-approach and standoff graphs, and a Stormer-limit check.
