+- `TripViewModel` loads `/api/trips` (with batch geocode of start/end via `/api/geocode/batch`)
+  and `/api/trip/{id}` for the route.
+- `TripListScreen` (new Trips tab): date/time, distance, duration, avg/max speed, start→end labels.
+- `TripReplayScreen`: MapLibre map using the Pi's offline raster tiles (`/static/vendor/tiles/{z}/{x}/{y}.png`,
+  zoom 8–15 — no internet needed), route polyline + cursor marker, camera fit, timeline scrubber
+  with timestamp + speed, and play/pause animation.
+- Deferred: Room offline cache, start/end markers, geocode label under the scrubber.
