"""torch-dimensions — N-dimensional sequence models for PyTorch.

Every model in scope is a 1-D mixer plus a plan for sweeping it over an N-D
lattice. See DESIGN.md for the architecture and PLAN.md for build order.

Conventionally imported as::

    import torch_dimensions as td

Public names land here as each phase completes, and optional-dependency blocks
are imported defensively so a CPU-only install stays importable.
