+| `HOME_LAT` | *(none)* | WGS-84 latitude of the home/property marker shown on the frontend map. |
+| `HOME_LON` | *(none)* | WGS-84 longitude of the home/property marker. |
+| `HOME_NAME` | `Home` | Display name for the home marker popup. |

+If `HOME_LAT` and `HOME_LON` are both set, the map is always visible. If only gates have coordinates (set per-gate in the admin panel), the map is shown only when at least one gate has a location.
