+## Optional Captain provider

+Set `GOCHAT_COPILOT_PROVIDER_CONFIG` and `GOCHAT_COPILOT_CHAT_API_KEY` in the
+ignored `.env` to enable Captain chat and embeddings. The JSON uses the same
+`chat`, `embedding`, `generation`, and `request` contract as the SuperAdmin

+`embedding.mode` is `separate`; runtime secrets are not written to the database.
