Assemble any of the 53 kit rigs parts cross-rig from the UI; genitals slot same-rig additive only. LODs land in library/garments/lod/ (subdir keeps scan() from double-listing). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Cross-rig parts are auto-fitted by assemble.py fit_part (cut-bone length

ratio). The genitals slot has no cut bone — it is attach_part only, and the

server refuses cross-rig genitals before we ever get here.
