// The C# 9 compiler emits a reference to this type for every `init` accessor and positional
// record (see Plugin/Operations/OperationTypes.cs). It ships with the BCL from .NET 5 onward;
// this project's target framework predates that, so the compiler needs it declared somewhere
// in the compilation. Purely a compile-time marker - no runtime behavior.
