// ── Engine guard ──────────────────────────────────────────────────────
// This setup file installs a vi.mock("@fusion/engine") that throws if
// the real engine is loaded. All plugin tests must mock "../pi-module.js"
// (the seam) to prevent the real @fusion/engine import chain.
//
// If you introduce a test that genuinely needs @fusion/engine:
// 1. Create a setup-test-isolation.ts (HOME override) following the
// pattern in packages/core/src/__tests__/setup-test-isolation.ts
// 2. Add it to setupFiles BEFORE this guard
// 3. Add a vi.mock("@fusion/engine", ...) override in the test file
// or a dedicated setup file to replace the throwing mock
