"""The browser playground stays wired to the public API it calls.

The playground runs hardcoded Python in Pyodide, so the only thing that can
silently break it from this side is renaming the API it imports. These guards
fail loudly if that happens. (The page itself needs a browser to test end to
end; see web/README.md.)
