☕ Lumped Cooling with Convection, Radiation and Heater (2D)

2D view of a warm body in a room: set its mass, heat capacity and conductance, add radiation, a power-law convection exponent and a heater, and compare the temperature curve with plain Newton cooling. Same lumped-capacity equations and RK4 as the 3D page, checked against the exact exponential, the equilibrium and an energy balance.
