Web Device layout component (this site) — not an AUP primitive; not an AUP Web-only widget; not a Markdown directive.
Site package: blocklets/arcblock/.web/components/period-index/. Resolution priority: site override > theme default.
Purpose
A dated collection as three stacked bands of decreasing density: ahead, recent, older.
Boundaries
- Site-only unless a theme package with the same name also exists (then this page is the override contract).
- Do not document AUP primitives or MD directives on this page.
- Do not invent props beyond the site
manifest.json.
Author entry
time-index layout
Common author-facing props (from manifest): items, dateField, endField, period, basePath, excerptField, metaFields, metaLabels, copy, variant, title, eyebrow, headingLevel
Surfaces
layout (and docs shell where mounted).
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 |
|---|---|
| Site package | blocklets/arcblock/.web/components/period-index/ |
| Manifest | …/period-index/manifest.json |
| Renderer | …/period-index/render.js (when present) |
| Internal matrix | docs/aup/capability-matrix.md §5 (internal, non-routed) |
| Matrix row concept | site layout-component · period-index |
Notes
Site-only period chrome.
