Description

this is cause there is no signed int64 in javascript. Check https://github.com/gzuidhof/zarr.js/blob/1002181a4c6b5411e20fe2bd54533a4c75b4bbcc/src/nestedArray/types.ts#L39-L67

this should happen at anndata and shapes/points level

Research direction

Start by comparing the referenced zarr.js src/nestedArray/types.ts definitions with the repository’s AnnData and shapes/points entry points. Trace where integer indexes are represented at both levels, then verify that they use int32 consistently and remain compatible with JavaScript consumers.
