1//! The handle an image travels in context under.
2//!
3//! The record of an image — where it was fetched from, how many bytes it is,
4//! where it lives — is the supervision domain's own; what every domain and
5//! every client must agree on is only how an image is named on the envelope,
6//! and that is this.
