- New `activeBody` field in config store with `setBody` action and URL sync (`b` key, defaults to `basic` for backward compat)
- Robot Body section in ConfigPanel between Persona Attire and Pricing
- RobotModel base mesh extracted into BaseBodyMesh subcomponent wrapped in error boundary so a missing EDU GLB silently falls back to basic
- Tests cover defaults, setBody, reset, and round-trip serialization
Note: drop `/public/Unitree_G1_EDU.glb` to enable the EDU variant — until then EDU selection falls back to basic with a console warning.
