AUP Web-only widget — not a cross-device primitive; not a Web Device layout component.
The name is registered in AUP_WIDGETS (packages/aup/src/aup-types.ts). It can be accepted by structure verification and implemented by a Web runtime (or native target where noted). It is not one of the 18 cross-device AUP_PRIMITIVES, does not enter DeviceCaps.primitives via fillPrimitives, and is not a Web Device theme/site layout component (for example content-card or page-breadcrumb).
Purpose
Compact two-column label/value layout for entity overviews and detail pages.
Boundaries
- Do not document this type as a portable primitive.
- Do not mix it with Web Device layout-component reference pages under
widgets/. - A parser-accepted name is not a portability or product-readiness claim.
Author entry
AUP type: "key-value-list". Showcase prim-key-value-list.
Surfaces
Interactive Web.
Fallback
No degradation chain.
