"""Public method namespace for the MacroLens unified API.

``import macrolens as ml; ml.methods.<ClassName>(task=...)`` resolves to
the registered concrete method class via the registry-driven
``methods/__init__.py`` package. This module is a re-export shim — every
attribute lookup is delegated to the underlying ``methods`` package's own
``__getattr__``, which performs the class-name → registered class lookup.

This file is intentionally lightweight; we avoid eagerly importing every
family module here (the underlying ``methods/__init__.py`` has already done
the eager import on first import of the package, so all classes are
discoverable through the registry).
