/* A small square icon button, bordered like the compact field it sits
   beside -- every "add to X" form (a kanban column, the inbox, the status
   list, the "all tasks" new-card form) used a full "Add" label until there
   were enough of them on screen at once to feel cluttered, then a borderless
   ghost icon on its own looked adrift next to that field. Excluded
   (":not(.btn-icon)" above and on the .field-row/.kanban__new overrides)
   rather than out-specificity'd, so it isn't at the mercy of source order --
   the same reasoning as .field's low specificity against input:focus. */
