-## Test layout
-
-Test modules under `tests/` are named after the source module they cover
-(e.g. `tests/layouts.py` covers `src/tensor_layouts/layouts.py`). Pytest
-is configured to discover **every** `*.py` file in `tests/`, so anything
-added there must be either a test module or pytest infrastructure
-(`conftest.py`). Shared helpers belong in the source tree or in a
-`tests/_support/` module that pytest does not auto-collect.
