One page shown inside another: a paragraph that is one link and one marker.

[Team header](/team-header.md)<!--sb include="body"-->

A marked link rather than a directive, and the reason is measured: this link is rewritten when its target moves, and an outside reader meets a working link carrying the author's own words instead of literal punctuation.

The link must be bundle-absolute, end in .md, carry no fragment and no query, and have a non-empty label. A relative path, a picture, a title, a second link in the paragraph or any words beside the link make it an ordinary paragraph, unchanged in the file. No near-miss is guessed into an include.

The marker must carry a value: <!--sb include--> parses to nothing and is therefore not one, which leaves room for a later include="summary" without a second mechanism.

Nothing of the target is stored — no cached title, no cached body, no hash. A page shown inside another is never a second copy of it. A page is never shown inside itself, at any depth.
