Not just "a" Python interpreter, not just "wraps", it's CPython (I
forget the version, maybe 3.10) compiled with WebAssembly as the
target platform with the Emscripten compiler (based on clang).

That means CPython is running natively on a virtual machine that is
available in almost all modern browsers, including those in your
phone, and the HTML incorporates it directly (not via Javascript)
using the same browser scripting API that Javascript uses.

Yes, this is alpha all the way down to the virtual machine.  Not sure
about the "leaks", the simpler demos in Peter's PyCon talk were pure
Python + HTML.
