OpenFreeMap's official repository describes its project code as MIT,
OpenMapTiles code as BSD-3-Clause, the Liberty-derived style design as CC BY
4.0, and map data as coming from OpenStreetMap. The hosted provider supplies
the actual style, sprites, glyphs, raster background, and vector tiles at
runtime; none is copied, cached, mirrored, prefetched, or redistributed here.

## Local renderer

MapLibre GL JS 6.7.0 is bundled locally under BSD-3-Clause. Its complete npm
distribution notice is [vendor/MAPLIBRE-LICENSE.txt](vendor/MAPLIBRE-LICENSE.txt).
The local files are upstream distribution copies verified by hash. V10 removes
only the trailing optional `sourceMappingURL` lines from the worker and shared
modules because their source-map artifacts are not bundled; runtime code and
the complete BSD-3-Clause notice are otherwise preserved.

No PMTiles runtime, local map archive, downloaded glyph, CDN code, remote app
font, analytics library, geocoder, or routing dependency ships in V10. Synthetic
location-context fixtures are project-authored contract examples, not copied
geographic source data.
