Web Device layout component — not an AUP primitive; not an AUP Web-only widget; not a Markdown directive.
Default-theme package: providers/runtime/web-device/themes/default/components/news-ticker/ (manifest.json + render.js). Resolved through the layout component chain (runtime surface → theme → optional site override).
Purpose
Scrolling news headlines driven by a data source.
Boundaries
- Do not call this an AUP primitive or put it under
docs/aup/primitives/. - Do not mix multiple layout components' contracts on this page.
- Manifest props are the author-facing contract; invented props are not portable.
Author entry
layout.aup
Common author-facing props (from manifest): items
Surfaces
layout (and narrow where the theme supports it). Not the document Markdown directive surface.
Public status
experimental
