   This exact declaration was written out in nineteen templates. The border and
   the ring around it are the focus marker; a text field matches :focus-visible
   even when it was clicked, so there is no separate mouse and keyboard state to
   tell apart here.

   The :root prefix buys one class of specificity, and it is load-bearing. Three
   templates still style the resting field through an attribute selector
   (`.form-group input[type="text"]`), which scores exactly the same as
   `.form-group input:focus` - and since this file now loads first, an even score
   hands the win to the template and the border never turns blue. Those selectors
   cannot simply be widened to `.form-group input`: they are narrow on purpose, to
   keep checkboxes and file pickers out.

   Forced-colours mode throws box-shadow away, which would leave those fields with
   no focus marker at all, so an outline stands in for it there. It carries the
   same prefix - without it the `outline: none` above would outscore it. */
