   box. It follows the heading's own alignment. Colour follows the banner
   it sits on: the site's muted text (--text-secondary) on light
   backgrounds, the banner sub-heading's light tone on the plum
   #inside-header, and the microsite sub-heading grey (#555) on the
   microsites' light banner, where --text-secondary would fall under 4.5:1. */
