Atlas at Scale — local original prototype, version 0.1.1 Made with Natural Earth. Map data are public domain. Source: https://github.com/nvkelso/natural-earth-vector/tree/ca96624a56bd078437bca8184e78163e5039ad19 Full source notice: LICENSES.txt We selected 28 map features, densified their great-circle edges, projected each with a local Lambert azimuthal equal-area projection, and normalised rendered shapes to unit area. Area ratios use the resulting low-resolution map estimates on a spherical Earth model. These are educational approximations, not official country areas or boundary claims. Small islands and details omitted by the source stay omitted. All game rules, interface, text, visual design, compass and share-card drawing are original. No Originle, Size It Up, TrueSize, map-tile, portrait, video, font or third-party game assets were copied. No network request is needed during play. Main-site shell integration 1 (2026-10-20): collection navigation points to /#games. In a same-origin host, an explicit collection-link click requests player exit through a source-checked message. Standalone sibling promotion links are omitted. The complete original license texts remain in this package.
