 ### Added
 
 - `spatialdata_io` ships a `py.typed` marker, so downstream type checkers use its annotations.
+- `atera` reader for 10x Genomics Atera bundles: cell-by-gene table, cell/nucleus labels and boundary
+  polygons, transcripts, and morphology images, read natively via `anndata`'s zarr IO.
+- `atera_to_proseg` converter: writes an Atera bundle's `transcripts.zarr.zip` to a `proseg`-compatible
+  `transcripts.parquet` (readable via `proseg --xenium`), streaming one spatial tile at a time.
