Their quickstart <https://zarr.readthedocs.io/en/stable/quickstart.html> uses .zarr as the extension and the v3 spec <https://zarr-specs.readthedocs.io/en/latest/v3/core/v3.0.html> says:

> When storing a Zarr hierarchy in a filesystem-like store (e.g. the local filesystem or S3) as a sub-directory, it is recommended that the sub-directory name ends with `.zarr` to indicate the start of a hierarchy to users.
