Web App

The Streamlit frontend (web/app.py) covers the 16 univariate distributions:

1. Pick Continuous/Discrete in the sidebar.
2. Choose a distribution; sliders are generated from get_parameter_bounds().
3. Inspect PDF/PMF + CDF (Plotly), random samples vs theory, full statistics, and the quantile calculator.

Advanced modules (multivariate, copulas, mixtures, fitting, Monte Carlo) are Python-API only by design — the web app stays focused and fast. The plotting facade used by both the app and library code lives in src.visualizers (plot_pdf, plot_cdf, plot_comparison) over src.utils.plotting.
