# Third-party notices

The current game uses the private European Atlas server engine and an independently authored 3D map. Coastlines use Natural Earth 10m land 5.1.1 (public domain). See Independent_Map.txt for map attribution.

Project source and editable models are not distributed by this website. Historical materials and their notices are retained privately outside the website assets.

## Historical power emblems

The seven badges use period heraldic artwork from Wikimedia Commons. Transparent margins are trimmed and all badges use a common 144 × 160 optical canvas, downsampled detail, lossless WebP encoding and a shared CSS aged-enamel treatment.
