Wealth that outlives a single run: name an heir, hold estates, and put assets into family trusts before they are taxed. The estate tax rate and the trust minimum are the engine's own constants rather than round numbers chosen for a design document.

Heirs age and trusts distribute on the simulation tick rather than on a button, so the page is about the decisions that change the outcome, establishing the dynasty and naming who inherits, rather than about clicking through mechanics the engine already runs.
