Replace the plain gray OpenStreetMap raster in the location picker with a
theme-aware CARTO basemap (no API key): sleek "dark matter" tiles under the
dark theme, colorful "voyager" tiles under the light theme, so the map
matches whichever is active. Swap Leaflet's default blue marker for an
accent-colored teardrop pin (the same glyph the Find button uses), and theme
the zoom controls + attribution to sit in the app's surfaces.
- mappicker.js: theme-aware CARTO tileLayer (retina, CARTO attribution);
L.divIcon "mp-pin" used for the marker
- style.css: .mp-pin styling, themed .leaflet-bar / attribution, map shadow
