"""
Stub module for the 'pyodide' package used in PyScript/PyOdide environments.

This module provides mock implementations for PyOdide functionality
that would normally be available through the 'pyodide' module in PyScript/PyOdide.
This allows the code to run in regular Python environments for testing,
development, or when PyScript/PyOdide is not available.
