/* ...with one exception. content/popup.css gives the bubble the maximum
   z-index, because on a host page it has to beat whatever that page stacks. On
   THIS page the only thing above it is our own tour overlay (lib/tour.css,
   z-index 9999), and the bubble outranking it put the callout for the
   Conjugate/Workbook/Save steps behind the very bubble those steps point into
   — arrow and all. Nothing on this page competes for the stack, so the bubble
   drops below the tour: the callout is legible, and the scrim dims the rest of
   the bubble around the one spotlit button. */
