   2. Visible keyboard focus

   users see no change.

/* !important is deliberate. The theme switches focus outlines off in several
   places (a:focus, button:focus, .btn--styleOne:focus, the newsletter input,
   the search overlay), some with more specific selectors than these. A visible
   focus indicator is the difference between a usable and an unusable site for
   anyone navigating by keyboard, so it has to win. :focus-visible means mouse
   users still see nothing. */

   4. "Listen to this page"
   A visible, labelled control - not an icon-only circle. Many of the people it
   helps most (low literacy, limited sight, no screen reader set up on a shared
   phone) will not recognise a speaker glyph on its own.
