◊(Local Yarn Code "View Ticket")

Articles should be able to specify the passage that will be used (or reused) as the excerpt in shortened listings. An inline excerpt would reuse an existing passage of the article or note as the excerpt. A non-inline excerpt would be filtered out of the article or note and only used in excerpted views.

A hypothetical ◊excerpt tag function would be passed through untouched in the doc and then snagged during the caching process in crystalize.rkt (similar to ◊note and ◊title).

If not supplied, an article or note's “excerpt” form would be the same as its “full” form. Excerpts will only be used when the note or article is too long to display fully in a listing context.

Article excerpts are done with [8af3b9ce0c30051a].

Separate ticket [23e419df24ec51ea] for excerpts in notes.
