Composition example images

PNG files are generated by the original Azimlib renderer from clean_map.py and composition_atlas.py. Natural Earth boundary data remain public domain, with provenance in the dataset guide. Routes and symbols are synthetic/original. Original example code is BSD-3-Clause (Kernerian). No Matplotlib code/assets are used to produce these images. The manifest records exact export hashes; PNG/SVG/HTML artifacts are retained separately for local validation.

The atlas is regenerated in the scientific batch with uniformly scaled custom legend symbols. The current manifest supersedes the earlier atlas export hashes; the stage-4 numeric report remains a historical installed capture.
