+<!-- Intentional divergence from the 1.1.0 baseline: UseRealFor's TService constraint changed
+     notnull -> class. No valid caller can break: TImplementation : class, TService already made a
+     non-reference TService uninstantiable (a class cannot derive from a struct, and interfaces
+     satisfy the class constraint). The tightening is required because AutoMocker's lazy factory
+     overload Use<TService>(Func<AutoMocker, TService>) cannot be bound when TService is merely
+     notnull - overload resolution against the class-constrained Use<TService>(Mock<TService>)
+     candidate fails with CS0452 under explicit type arguments and binds the wrong overload under
+     inference. Lazy creation + automatic disposal of UseRealFor instances depends on that factory
+     overload. -->
