/// Suite-wide setup: applied by `flutter test` to every test file below.

/// The test host is Linux, so every `Platform.isLinux` desktop branch runs
/// here -- including the one that stores the Firebase refresh token in
/// `~/.config/screen_locker/firebase_auth.json`, the live credential the
/// screen-locker daemon signs in with. A sign-in test once overwrote it with
/// fixture values and still passed. Each test now gets its own throwaway
/// config root instead; `desktopConfigRoot` refuses the real one under
/// `flutter test`, so a test that slipped past this fails loudly.
