 5. Watch the case open or close with sound feedback.
 6. Interact with repair module slots to cycle/select repair models.
 
+The production repair flow is now being moved toward reusable mission data for `bike`, `pylone`, and `ferme`. This lets the same future `RepairGame` component read one mission config instead of duplicating per-mission setup.

 ## Why It Matters
 
 This feature validates the core repair fantasy before a full mission system exists. It tests whether repair objects, physical proximity, model selection, audio feedback, and exploded model visualization can work together in the 3D scene.

-- There is no central `GameManager` or Zustand store in this branch.

 - Hand tracking is available as debug interaction input, not as final repair gameplay.
