{%-comment-%} lists pages as section cards given a pages array

inputs: none dependencies:

pages:                  the pages array to render
site.static_files:      to lookup and make sure a placeholder.png file exists
site.show.authors:      to determine whether to show authors
site.show.page_authors: to determine whether to show authors
site.people:            to lookup authors in the people array
site.title:             to use as the author, as a last resort

local:

published_pages:        pages filtered for `published==true`
placeholder:            placeholder.png file to use in case no other page image is available
auth:                   the author's handle, used for unpublished authors in place of their name
author:                 the looked-up author in site.people
