Research direction
Reproduce the linked Shinylive app and inspect the traceback at /lib/python3.11/site-packages/shiny/reactive/_reactives.py:559. Determine why MockKernel lacks showtraceback and identify the project entry point responsible for handling this error. Done means the app no longer raises the reported AttributeError and the resulting error handling is verified.
