Represents global properties of a finalized composition.
This struct holds derived quantities that describe the entire composition, such as mean particle mass. It is typically returned by {\ttfamily\doxylink{classfourdst_1_1composition_1_1_composition}{Composition}} methods after the composition has been finalized and is intended for internal or advanced use.
