A p/ package denotes a "pure" package within the system. These packages are
crafted as self-contained units of code, capable of being independently imported
and utilized.
Unlike r/ realms, p/ packages do not possess states or assets. They are
designed specifically to be called by other packages, whether those packages are
pure or realms.
An r/ realm designates a package endowed with advanced capabilities, referred
to as a "realm".
Realms can accommodate a diverse array of data and functionalities, including Bank State, Data State, and Address.
They are purposed to furnish and expose features for both user-initiated calls and as components invoked by other realm packages.
