Transclusions are an extension of the Markdown syntax enabling inline embedding of content.

The general syntax is ![[path]]. Two types of transclusions are currently supported:

Media

Syntax: ![[path/to/image.jpg]]. See Document#Embedding for more details.

Transclusions already support images, audio, video, and PDFs using the browser’s corresponding media elements. Local media is served through range-capable /.fs responses, so playback seeking and incremental PDF loading use the same server and service-worker behavior as full-document media viewing.

Media resizing is also supported:

Pages

Syntax:

• ![[page name]] embed an entire page
• ![[page name#header]] embed only a section (guarded by the given header)

Text and source documents are not transcluded as highlighted source. The editable text-document fallback does not change this boundary: page transclusion remains limited to Markdown pages.
