Research direction

Start with src/resources/jupyter/jupyter.py at line 28 and read the asyncio policy deprecation documentation linked in the issue. Reproduce the warning while rendering with Python 3.14 on Windows, then verify the updated behavior does not emit these deprecation warnings and remains compatible with Python 3.16.
