"""Export ``geometry.build_components()`` to ``../components.json`` (2026-10-21).

The runtime (``dishsim_frigidaire.geometry.components``) reads this file instead of rebuilding the meshes: per
component its mass, visual meshes (material, points, faces), wire paths ``[name, path, radius]``, solids, sites and
site quaternions. JSON keeps every float exactly (repr round trip). Normals are not exported (nothing reads them).
