Detailed Description

Gravitational N-body simulation — raylib visualiser.

Demonstrates num::ode_verlet (symplectic) vs num::ode_rk4 on three classical scenarios, plus a galaxy-collapse scenario with body merging.

Controls: 1 / 2 / 3 / 4 – switch scenario V – toggle Verlet ↔ RK4 SPACE – pause / resume R – reset current scenario +/- – increase / decrease simulation speed F – toggle trail fade
