+    # GPU SUPPORT NOTES:
+    # 1. The "deploy" section is ignored by classic 'docker-compose'; it's honored in Swarm.
+    # 2. For local 'docker compose up' with NVIDIA GPUs you need the host configured with
+    #    nvidia-container-toolkit. Then either:
+    #       a) Leave the reservation block (Compose V2 now honors it) OR
+    #       b) Start with: docker compose up --build (Compose will request GPUs) OR
+    #       c) Explicitly override: docker compose run --gpus all ollama
+    # 3. If your Docker/Compose version does NOT honor the reservation below, uncomment the
+    #    'devices' section further down as a fallback (less portable).
