/* The capability explorer.
 *
 * One grid holds the headings and the panes. On a wide screen the headings stack down the left and
 * every pane sits in the same area on the right, one shown at a time. Under 768 the grid collapses
 * to one column and the natural document order, heading then its own pane, is already an accordion.
 * That is why the buttons and panes are siblings rather than two separate lists: one copy of every
 * heading in the DOM, in reading order, with no duplication for a second layout.
 *
 * Every selector is prefixed cx- so nothing here can collide with the site's own classes.
