- stage: detectVisemes() maps CC/ARKit/plain morph names -> canonical
A/E/I/O/U/MBP/FV/L at character load; visemeTargets(id) + setMorph(id,name,w)
for the timeline to drive lip sync; visemeSelfCheck() asserts the matcher
- dock: inspector 🗣 badge (greyed when a rig has no mouth morphs)
- stage: camera/light default source:{type:'none'} (PLAN §4.1); applyState
skips only upload mesh/backdrop bytes -> rig survives save/load (SYNC4)
Verified live at :8020: selfcheck ok=[A,FV,L,MBP,U]; save/load keeps cam+light.
