AFS_Adom flight computer molecule

"""AFS_Adom project reel: title card, routing build-up (gen/buildup.py), then real recorded step clips from the aiflow run
(pours filling, each power net lit, silkscreen going on, Adom Fields current/heat, the finished board in the KiCad 3D
viewer), end card. Each segment normalised to 1920x1080 30 fps with a caption bar; chapters written for ::adom-video."""
