Add a collapsible, pulsing architecture diagram to the Knowledge Chat that
visualizes the real RAG pipeline in two rows: Index (Upload -> Docling ->
Split -> Embed/MiniLM -> ChromaDB) and Query (Question -> Embed -> Retrieve
-> Context -> LLM -> Answer), badged with the actual stack (LangChain,
ChromaDB, Docling, sentence-transformers).
Connectors have a flowing dashed track plus a traveling glow dot and nodes
pulse; the whole flow speeds up while the chat/ingest is busy. Honors
