+//! Naming a segmented person from the face inside it.
+//!
+//! `dr-segment` recognises *a person*; this crate recognises *which* person.
+//! Putting the two together costs one containment test and turns "person" in
+//! the mask list into "Anna" — which is the difference between a vocabulary of
+//! eighty COCO classes and a vocabulary that includes the user's family.
+//!
+//! Pure geometry: no model, no catalog, no Slint. The caller supplies boxes and
+//! names from wherever it keeps them.
+//!
+//! # Why containment and not overlap
+//!
+//! A face is a small part of the person it belongs to, and it is *inside* them.
+//! Intersection-over-union would be near zero for a correct match — the face is
+//! perhaps a twentieth of the person's area — so IoU is the wrong measure
+//! entirely here and would reject every true pairing.
