   SGrid: the data grid. Colours are tokens only, so it is right in both themes;
   sides are logical (inline-start/end), so it is right in Arabic.

   The feel: a quiet frame, a toolbar that is there when wanted, headings that
   say what they sort and filter without shouting, figures on their last digit,
   and the row under the pointer or the keyboard always plain to see.
