   The previous version relied on :hover plus :focus-within, and was unusable
   on an iPad: there is no hover on touch, and Safari does not give a <button>
   focus when you tap it, so neither selector ever fired and the menu simply
   could not be opened. A checkbox is the one thing a tap reliably toggles
   without JavaScript, which is the same reason the mobile burger uses one.
