- Drop the fitBounds-to-markers logic so the map always opens at the same
Berlin-wide view (center 52.52/13.405, zoom 11), regardless of pin count
- Swap OSM standard tiles for CartoDB Voyager — cleaner, more
Google-Maps-like base style
- Add OpenRailwayMap overlay (opacity .75) so S-/U-Bahn/Tram lines are
highlighted on top of the base
- CSP img-src widened to cover the new tile hosts
