data_handling._offline_store

Low-level storage primitives for the VIN offline dataset format.

This module owns the immutable on-disk layout of the VIN offline dataset:

path and split configuration,
per-shard block materialization helpers,
manifest and sample-index loading, and
Zarr-backed random-access reads for fixed-size tensor blocks.
indexed per-row MessagePack reads for optional diagnostic payloads.
