Sample

Source:

markdown

Rendered:

A read-only example

Content and layout are maintained separately

The body can contain paragraphs, lists, and code.

  • A content item owns the reader-facing text
  • layout.aup decides how a page organizes those items

An info-card is not a link. Even if an author supplies an href, the current content reader does not promote it to a clickable card.

Failure and limits

SituationExpected result
href on info-cardIgnored for navigation
Expecting click-through cardUse link-card instead
Outer fence too shallow for bodyBody may drop / misparse
