"""STRATA data acquisition subpackage.

The registry and manifest data models depend only on the standard library plus
PyYAML. The network download dependencies (``huggingface_hub``, ``requests``) are
imported lazily inside :mod:`strata.data.acquire`, so registry/manifest logic can
be exercised (and unit-tested) without network libraries installed, and so
``HF_HOME`` can be configured before ``huggingface_hub`` initializes.
