The configuration singleton, seen through its complete contract.
This is the single widening cast of the module — it stands exactly where the
two-stage assembly happens, and it is why the three grafting siblings need no cast of
their own. Widening here rather than at each call site also means a member added to
ConfigFacade but grafted by nobody now fails at its first use instead of silently
resolving to undefined.
