   ZDR beam — "Zero Data Retention" hero animation
   A document of context travels from beside Wisbid to the model
   provider and fades; the response emerges at the provider and
   returns to Wisbid. The document never overlaps the endpoints.
   The governance panel (.gv-visual) is the only frame.
