/// The share sheet must always get a non-empty anchor rect.
///
/// iPad and macOS present it as a popover and `share_plus` throws a
/// PlatformException when the origin is missing or zero-sized. Share calls are
/// typically the last await in a button handler, so that exception goes
/// unhandled and the button silently does nothing — which is how the device
/// diagnostics export appeared broken.
