   widgets often add a vertical margin to all `details` (e.g.
   `.foo details { margin: 8px 0 }`). Either would offset one action-row
   button vertically and break alignment with its sibling.
   The doubled `.fv-action-row.fv-action-row` is a deliberate
   specificity-bumping technique (raises this rule from 0,1,1 to 0,2,1)

   `.foo details { margin: ... }` (0,1,1) regardless of source order. */
