-### Geocoding & Address Lookup
+### 📍 Geocoding & Address Lookup
 To resolve coordinates to readable address labels (e.g., city/country) and enable searching for locations without relying on proprietary Google Play Services, BoxViewer integrates open-source OpenStreetMap (OSM) data backends:
 *   **Photon Geocoder**: An open, privacy-friendly search and reverse-geocoding service powered by OpenStreetMap data, operated by **[komoot GmbH](https://www.komoot.com)**, Berlin, Germany.
 *   **Nominatim Geocoder**: An open-source search and reverse-geocoding engine for OpenStreetMap data, operated by the **[OpenStreetMap Foundation](https://osmfoundation.org)**.
 
 We are extremely grateful to the **OpenStreetMap contributors** for providing the underlying open map data that powers the geo features of this app.
