Why does my Kaggle notebook look like JSON

Question

I think I've broken my Kaggle notebook: When I open the notebook in Kaggle, what I see on the screen is the JSON that represents the notebook contents rather than the notebook itself. Apparently, it's not completely clobbered, since I can download it as a .ipynb file, and when I open that file in a local copy of Jupyter, it looks as I would expect.

Oh, OK, I just clicked on [Edit] and now the notebook looks like a notebook.
