/* Site footer: brand column + four link columns, copyright bar with payment logos. Shared by every page.
   Layout is intrinsic: the brand column sits beside the links while there is room (>= ~920px) and above them
   otherwise; the link columns go 4 -> 3 -> 2 across by themselves. Mobile spacing is ~35% tighter. */
