/* ============================================================
   COMMIT — shared site chrome
   Layers on tokens.css. The single definition of the components
   that appear on more than one page: the brand lockup, buttons,
   and the header/footer row.

   PADDING CONVENTION (read before touching a header/footer):
     • .wrap owns HORIZONTAL padding (tokens.css).
     • the full-width parent (nav / header / footer / section)
       owns VERTICAL padding.
     • .row owns NO padding.
   A `padding` shorthand on a .wrap/.row element out-specifies
   .wrap and zeroes its sides, bleeding the bar to the screen
   edge. Keeping padding off .row is what prevents that — don't
   add a `padding` shorthand to a row.
