How these are made
The prose is written for these pages; nothing is excerpted from the paid lessons. Every figure in a table is produced at build time by the product’s financial domain code, and a test suite recomputes each one independently before a page can ship. Claims about law or standard documents cite their primary sources. The full method is described on the about page.
