+Zarr Python 3.1.4 adds [`zarr.experimental.cache_store.CacheStore`][] provides a dual-store caching implementation
 that can be wrapped around any Zarr store to improve performance for repeated data access.
 This is particularly useful when working with remote stores (e.g., S3, HTTP) where network
 latency can significantly impact data access speed.

 Creating a CacheStore requires both a source store and a cache store. The cache store
 can be any Store implementation, providing flexibility in cache persistence:
