Build a Complete Langfuse Observability and Evaluation Pipeline for Tracing, Prompt Management, Scoring, and Experiments

The tutorial shows how to set up Langfuse for LLM observability, tracing, and evaluation.

It traces function calls and a small RAG workflow while managing prompts centrally.

The pipeline attaches evaluation scores and supports dataset-based experiments.

Experiments can run with either a real OpenAI model or a deterministic mock backend.
