# MD session recon -- run FIRST thing next bridge session:

#
# 1. Harvests pybind11 docstrings (all overloads) for every function the
#    t-shirt build needs -> tools/md_bridge/api_docs.json
# 2. Imports the Lena avatar FBX (tools/tailor/avatar/Lena_QuatSkin_Avatar.fbx)
# 3. Lists arrangement points, snapshots the scene
# Defensive: each step reports independently; nothing dies on the first surprise.
