Additional Context for Reviewers

• I passed tests locally for both code (pytest) and documentation changes (uv run jb build docs --builder=custom --custom-builder=doctest)

Note

Medium Risk
Mostly documentation/doctest expansion, but it adds a large amount of executable doctest content that could break doc builds or become flaky if outputs change.

Overview
Adds a new Friedland docs section to the JupyterBook TOC and updates the Friedland landing page title styling.

Greatly expands docs/friedland/chapter_7.rst from a brief intro into a full, step-by-step (doctested) reproduction of Friedland Chapter 7 exhibits, including reported/paid development, multiple averaging methods (including geometric), explicit selected patterns with DevelopmentConstant + TailConstant, rounded CDF/ultimate calculations, and helper functions to generate summary/unpaid exhibits; Exhibit III is left as WIP.

Unprofessional "fake" language in published documentation text

Low Severity

The text We will also fake some geometric averages. reads as a personal draft note rather than polished documentation. The word "fake" is ambiguous — it's unclear whether the results are fabricated or if this is a placeholder for a real section.
