Module entry point

The __init__.py simply re-exports the Lib class:

"""Reusable container helpers: base images, timezone, user setup, DinD, etc."""

from .main import Lib as Lib

The main.py defines the @object_type class that composes all the functions defined in the use-case org files. Besides image versions, the class carries a default_username field so the container user is defined once and overridable globally — individual functions default to None and fall back to self.default_username. The timezone field (default Europe/Paris) controls which timezone is set in all container variants.
