# Travel basemap

`travel-dark.json` is adapted from [OpenFreeMap Dark](https://tiles.openfreemap.org/styles/dark), retrieved 12 October 2026, based on [OpenMapTiles Dark Matter](https://github.com/openmaptiles/dark-matter-gl-style). Changes: charcoal palette, fewer detail layers, no buildings or extra icons, and street labels at closer zoom levels.

Map data is from [OpenStreetMap](https://www.openstreetmap.org/copyright), served by [OpenFreeMap](https://openfreemap.org/). The style's original license follows.
