- napari generative zarr: link to relevant part of PR and the yt in napari generative zarr experiment
- sph frontends: should be fairly straightforward to implement a frontend for an sph code with a zarr-hdf backend.
- grid-based: uniform or stretched grids with no refinement also should be simple-ish
- grid-based, refined: refined grids are a little trickier... could implement a custom zarr store that fills at a given refinement level (similar to a YTArbitraryGrid). this would kinda look like napari's generative zarr
