Treatment by Pattern: projected to a display SVG with longitude scaled at
9 degrees north, display coordinates rounded to 0.1 pixel, uniform state
fills, layered copies and decorative evidence points and branching paths.
The provider's simplified polygons are retained; no administrative units
are invented or redrawn. Depth is illustrative, not terrain or elevation.

The nodes and paths are conceptual. They do not represent actual incidents,
cities, infrastructure corridors, risk levels, or institutional results.
This illustration is not a legal or survey boundary reference.
