Goal: Adjust your μ and σ so the green model curve overlays the histogram of data. Higher score (less negative) is better. Try to match the hidden parameters without revealing!

Details
Score = average log p(xᵢ | μ,σ) over current sample. "Auto‑fit" sets μ̂, σ̂ to the sample mean and standard deviation (MLE for Normal with unknown mean/variance).
Hint updates as you move: if your curve is too narrow/wide it will say so; likewise for mean alignment.
