Adjust the parameters below to simulate a Stochastic Partial Differential Equation integrating spatial food diffusion and random market volatility. The 3D surface updates based on: \( dF = \left( \alpha C N u_p - \min(\beta P, F) - \gamma F + D_F \frac{\partial^2 F}{\partial x^2} \right) dt + \sigma_F F dW_F \) \( dC = \left( p_{margin}\min(\beta P, F) - c F - (u_s + u_e)C + D_C \frac{\partial^2 C}{\partial x^2} \right) dt + \sigma_C C dW_C \)
