// Shared runtime integration fixtures and test implementations.
// Domain-focused suites in sibling files call into these functions so coverage

//
// This file now focuses on domain-specific test logic, while reusable
// provider implementations and shared harness helpers have been moved to
// runtime_providers.rs and runtime_helpers.rs respectively.
