+// Vitest cannot transform React Native's Flow-typed source. We redirect
+// every `react-native` reference to a minimal host-component shim
+// (`vitest.rn-shim.ts`) so @testing-library/react-native v12 + jsdom can
+// render the few primitives PinInput uses.
+//
+// Two interception layers are needed:
+//   1. resolve.alias  — covers ESM imports vite sees during transformation
+//      of inlined dependencies (e.g. when @testing-library/react-native
+//      goes through vite's pipeline because of `server.deps.inline`).
+//   2. setupFiles patches Module._resolveFilename so any pure-CJS
+//      `require("react-native")` that escapes vite also lands on the shim.
