FastHTML requires apsw (SQLite wrapper) even if you don't use it. We already compiled apsw to WASIX but it also requires publishing a new version of Python to Wasmer (with sqlite dynamically linked instead of statically linked).

We will release a new Python version by the end of this week / beginning of next one, so by then FastHTML should be fully work in Wasmer! (both runtime and Edge)

Sounds awesome!
