+K2 Think Integration: Explainable AI for Q-TensorFormer.
+
+Uses the K2 Think API (MBZUAI-IFM/K2-Think-v2) to generate natural language 
+explanations for the model's decisions:
+- Why a specific tensor rank was chosen
+- Why certain tokens were routed to quantum
+- What the entanglement entropy means
+
+This demonstrates how Q-TensorFormer can produce explainable compression decisions
+using an external reasoning LLM.
