At the top of every "What can this map do?" panel: a "Short description" header and the map's
intro, on a pale band with the Rudder blue as its accent bar and the text in a darker shade of that
blue (5.6:1), so the eye finds it first. Below it, the strategy is a collapsed "Strategy ▾" disclosure
(a native details element, collapsed again on every open) instead of a tab; the examples follow
wherever a map has them. The tab machinery goes. New label mapInfo.shortDescription in all 11
locales.
