/// Visual harness for the Deliveries tab's two public pieces.

/// `_MyPickupsState` cannot be pumped — Get, SharedPreferences, Geolocator and
/// a 3s poll — and the queue's three quieter tiers (`_NextCard`, `_LaterRow`,
/// `_SkippedRow`) are private to `card.dart`. What is reachable is exactly the
/// pair the redesign is about: [TripProgressRail], which is the head of the
/// screen, and [PickupCard], which is the one live card under it.
///
/// The rail is shot at four route lengths because the documented gap against it
/// is that "a 21-stop route overflows it" — a claim about layout, which is
/// answerable by looking. Run with `--update-goldens`.
