/// ACCEPTED PILL — how many stops you have taken, and the way to them
///
/// Home is where the rider *decides*; Bookings is where he *works*. The bridge
/// between the two used to be a "Continue trip" button sitting under the last
/// hub row of a trip — which meant it only existed once that particular trip
/// had nothing left to decide, it moved as the route grew, and it was below the
/// fold on any route longer than about four stops. A rider who had accepted
/// three stops and scrolled back to the top had nothing on screen telling him
/// so, and no way through.
///
/// This says both things in one control, in one fixed place: **how many
/// bookings he is holding**, and one tap to go work them. It is the counterpart
/// to [SelectionBar] — that one is about the stops he is choosing, this one
/// about the stops he has already taken — so they share the floating slot at
/// the foot of the page and never appear together. A selection in progress is
/// the more urgent of the two and wins the slot.
///
/// The count comes from the accepted store, which drops a booking once it is
/// picked, so the number is "waiting for you on Bookings" rather than "accepted
/// at some point today".
