/// Home's empty branch rendered `SizedBox.shrink()` — literally nothing — so a
/// rider whose hub had not assigned him anything opened the app to a blank
/// screen and could not tell it apart from one that had failed to load. Two
/// very different situations, one identical rendering: wait, or report it.
///
/// The empty state itself was never missing; it was orphaned when the trip tabs
/// were removed and nothing called it any more. This pins the wiring, because
/// the failure is silent — everything compiles and the screen just goes quiet.
