Central Config with all tunables (retention, GPS timeout, colors, event type keys, menu item metadata). Event / EventStore handle persistence via Application.Storage with 7-day pruning. Logger mirrors the same retention. LayoutMetrics and Haversine provide resolution-independent geometry helpers. German UI strings and placeholder menu icons landed alongside so the build stays green.
