Module storage 

Persistent key-value cart storage: the save file.

Carts reach this through four ABI imports (storage_set / storage_get / storage_remove / storage_clear, see docs/ABI.md); values cross the boundary as JSON text and live here as parsed serde_json::Values. Native frontends back the store with a JSON file under the user’s cache directory, keyed by cart name; the web player and headless verify keep it in memory. The whole store serializes to at most 128 K — the same one number as every other cart limit (docs/LIMITS.md).
