Feature Name: The "Equanimity Engine" (Interactive Volatility Simulator)

The Concept: Instead of just reading about staying calm during market crashes, this feature turns the PDF into a stress-test simulation. It transforms the static text into an active sandbox, allowing the reader to visualize the consequences of panic-selling versus holding steady using their own portfolio data.

Personalized Takeaways: After the simulation, the feature auto-generates a personalized watermark on the PDF page that says: "Your strategy requires X amount of patience. Historical recovery time: Y years."

1. Has my long-term objective changed?
2. Has new information materially altered underlying fundamentals?
3. Would the decision look sensible if prices were 50% higher or lower?

7. Diagnostics and model checking

• Posterior predictive checks: Compare simulated marginals (integrating volatility) to observed histogram, QQ-plots.
• Tail-index estimation: Hill estimator or bootstrapped tail tests to confirm heavy tails expected from mixing.
• Residual analysis: For hierarchical fits, inspect inferred V distribution for plausibility and independence.
• Likelihood-ratio tests / information criteria to compare models with and without volatility mixing.
