   `.btn-sm` is 36px, which is right for a mouse and wrong for a finger. It is
   the most common control in Screen A — measured 8 to 15 of them per section —
   so on a tablet the whole panel was below the 44px target the spec asks for.
   Keyed on `pointer: coarse` rather than on width, because the thing that
   decides is the input device: a 1280px touchscreen needs the big targets and a
   900px window with a mouse does not. */
