+/// \brief Canonical MafiaNet type aliases over the legacy RakNet names.
+///
+/// The library lives in the `MafiaNet` namespace, but many public types still
+/// carry their historical RakNet names. This header introduces clean, canonical
+/// aliases so callers can write idiomatic MafiaNet code:
+/// \code
+/// MafiaNet::PeerInterface* peer = MafiaNet::PeerInterface::GetInstance();
+/// \endcode
+///
+/// These are `using` aliases (not subclasses): each canonical name denotes the
+/// exact same type as its legacy counterpart, so the two interoperate freely.
+///
+/// \note Aliases only — the legacy declarations are intentionally left untouched
+/// and un-deprecated. A `[[deprecated]]` pass is a separate, later task.
