- User-supplied photographs — visual reference for the slender silhouette, red warning lamps, dense vertical wires and grated service structures. They have not been redistributed in this demo.

Platform spacing, ladder dimensions, the 88–100 m demonstration section, and hatch operation are gameplay interpretations. The surrounding terrain is illustrative, not a map. This slice does not reconstruct site security.
