Environment helpers

persona_data.environment keeps small runtime utilities shared across the persona projects.

from persona_data.environment import get_artifacts_dir, get_device, set_seed

set_seed(1337)
device = get_device()
artifacts_dir = get_artifacts_dir()

Helpers

Helper	Behavior
set_seed(seed)	Seeds Python random, NumPy, Torch CPU, CUDA when available, and MPS when available.
get_device()	Returns cuda, then mps, then cpu based on local Torch availability.
get_artifacts_dir()	Returns Path(os.environ["ARTIFACTS_DIR"]), or Path("artifacts") when the variable is unset.

Torch and NumPy are imported lazily inside set_seed / get_device, so importing this module (e.g. for get_artifacts_dir) stays cheap in data-only contexts.
