This template is primarily called from Template:Card infobox and uses the parameters from that template, which are drawn from a card page's associated data page. This page feeds the data into their associated parameter slots and creates the styled infobox that is then returned to the cargo query and rendered on the page. It also generates the first line of text on the page describing what the card is. Furthermore, this templates sets a custom
og:description attribute on the page so that search engines like Google don't parse the Card infobox as the search description.
