+"""LoRA fine-tuning for causal LMs.
+
+Designed to be invoked from llm-trainer dashboard. Streams structured progress
+events via stdout so the dashboard can render real metrics instead of tailing logs.
+
+Progress events are single-line JSON prefixed with [METRIC]:
+    [METRIC] {"type":"metric","step":12,"max_steps":120,"loss":1.83,...}
+
+Status events use [STATUS] for non-metric milestones:
+    [STATUS] {"phase":"loading_model","detail":"meta-llama/Llama-3-8B"}
