Guidance to review

Non-streaming (SSR)

• Visit /sessions/ with USE_STREAMING=False in your .env

STREAMING (CSR)

Because the Django endpoint isn't streaming markdown yet, it's best to use the Node.js websocket demo:

• Run the node.js demo at /app/frontend/streaming-ai-response/ (it has its own readme)
• Set USE_STREAMING=True in .env
• In settings.py temporarily add "*" to CSP_DEFAULT_SRC
• In sessions_view in views.py update endpoint = "ws://localhost:8888"
• Visit /sessions/ and generate a response. Some words will be **bold**
