//! Replaceable storage for opaque blob bytes.
//!
//! A blob store knows nothing about accounts, MIME types, or database rows. It
//! receives a namespaced key and bytes. Implementations can therefore target a
//! filesystem, object storage, an encrypted vault, or a test double without
//! changing repository behavior.
