Downloaded 2026-09-08. This is the source's simplified national land geometry,
not de facto control or front lines. Crimea, Sevastopol, Donetsk and Luhansk
are included. The website uses outer rings, projects them onto a sphere, and
adds a colored visual accent. The geographic coordinates are unmodified.
No internal regional boundaries are rendered. Kyiv's beacon is an additional
design annotation, not part of the source.

The source organizations do not endorse ROSA. Full boundary data remain
available alongside the visualization. Source and license links appear in the footer.
