"""Cuentas Claras — deterministic tax & finance engine.

This package is the trust foundation of the app: it contains *all* the arithmetic
and *no* model. Every function returns a :class:`CalcResult` carrying the figure,
its step-by-step breakdown, and the dated source it came from. The LLM orchestrates
and explains these results — it never computes them.
