+## Embodiment Boundary
+
+Embodiment is part of the prompt surface, not flavor garnish. If a character is
+a cetacean Navigator, the response model must know what kind of body is acting
+and what infrastructure surrounds it.
+
+For Navigator scenes, project habitat-native affordances directly: channels,
+wet/dry workstations, shared displays, control rails, acoustic or translation
+systems, and other infrastructure built around cetacean movement and
+communication. Do not let the model default to hands, pockets, standing,
+walking, leaning, or doorway blocking unless the fixture explicitly establishes
+that visible interface.
