Same chrome as a doc page — sidebar, header, sticky bar with a close, pager, feedback, footer — around a body you write as HTML rather than markdown. The difference you can see is the width: no 1080px measure, and no table-of-contents rail.
Reach for this when the content is not prose. A wide comparison table, a gallery, a diagram: things the reading measure would crop for no benefit. If the body is prose, use the doc type — the measure is doing real work there.
The body is injected verbatim. It never goes through
markdownToHtml, so nothing is rewritten underneath you: the table
below keeps the classes it was given, and no copy buttons appear in code
blocks you did not ask for.
| Slot | Doc | Page | Why |
|---|---|---|---|
| Body | Markdown | HTML | Prose wants the pipeline; markup does not |
| Measure | 1080px | Released | The measure serves reading, not layout |
| Contents rail | Yes | No | It comes with the measure, as one decision |
| Sticky bar, pager, footer | Yes | Yes | A page is still a page in the book |
