🌌 Cosmic Inflation: 2D Hubble Horizon Diagram

2D view of slow-roll inflation driven by a scalar field: the Friedmann and field equations are integrated live, the comoving Hubble radius shrinks while draggable comoving modes exit the horizon, and a top-down particle map shows fluctuations freezing. Reports the spectral index and tensor ratio for three potentials.
