You know, immutable enterprise systems.
I installed HeliumOS (Almalinux bootc) on a corebooted Chromebook. Works really well, but audio needs to be configured.
The script needs a recent python which is not available there.
Go and rust can be installed for a user only. Is there something similar for python?
Perhaps overkill for your use case, but uv is pretty great. I suppose you could just use it to install a local python and then add it to your path.
This was going to be my recommendation as well.
