-{# Somewhat ironically, we take away the ability for case studies to be
-   represented by their title paragraph.  Because we *don't* use the title
-   paragraph for the main listings on the front page and the /work page (both of
-   which use the tile view mode, which uses only set regular fields), the use of
-   the title paragraph for search results (and anywhere else we use teasers)
-   would be a surprise— the summary field, while also not used on the listing
-   pages, is at least consistently used across multiple content types.
