// Production behavior is 100% unchanged — only the test sees the fast values.
// Original values are restored via t.Cleanup so parallel/sequential tests
// remain isolated.
//
// Use in any test that exercises callClassifyWithRetry / chatWithRetry with
// >1 attempt. Do NOT use in tests that explicitly assert on the default
// values (e.g. TestCallClassifyWithRetry_RetriesAndBackoffs).
