+#
+# - **Python Inference (PEFT)**: Load base model + adapter as shown in Section 9.
+# - **Merged model**: Set `DO_MERGE=True` to create a standalone model directory; you can then convert to other runtimes (e.g., llama.cpp GGUF) using their conversion tools.
+# - **Ollama**: If your runtime supports adapters or merged weights for the chosen base model, create a `Modelfile` pointing to them. Need a concrete path? Tell me your base and target runtime and I’ll add exact steps.
