- Alerts (live + real-data test) carry the station name + coordinates in
userInfo and attach a map snapshot with a red pin, so the expanded
notification shows where the station is
- Tapping a notification opens Apple Maps driving directions to the
station from the user's current location (maps:// daddr)
- If Apple Maps hand-off fails (LiveContainer), an in-app map sheet
(StationMapView) pins the station + user location with a Directions
button
