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/platform-stack/ (manifest.json + render.js). Resolved through the layout component chain (runtime surface → theme → optional site override).
Purpose
Layered technology-stack diagram with optional highlight for the current product or technology.
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): highlight, highlightLayer, compact, layers
Surfaces
layout (and narrow where the theme supports it). Not the document Markdown directive surface.
Public status
released

Sample
No isolated docs-safe live mock on this page. The contract is proven by site pages that mount this unit in layout.aup (or the docs shell). Copy author source from the evidence paths; do not invent props beyond the target manifest.json.
Evidence
| Item | Path |
|---|---|
| Theme package | providers/runtime/web-device/themes/default/components/platform-stack/ |
| Manifest | …/platform-stack/manifest.json |
| Renderer | …/platform-stack/render.js |
| Internal matrix | docs/aup/capability-matrix.md §3 (internal, non-routed) |
| Matrix row concept | layout-component · platform-stack |
Notes
Layers come from site content bindings.
