"""Tabular helpers (parquet/zarr) — removed.
This module formerly provided helpers to load Parquet and Zarr assets into
an xarray.Dataset for the estimation fallback path. The parquet/zarr-based
fallback was intentionally removed in this change. To avoid import-time
errors in remaining code or tests, we keep a minimal stub that raises a
clear error if used.
