   Layout: a four-column grid — brand / For students / For employers / About —
   that becomes two columns at 1000px (the brand block spanning the full row)
   and one at 500px. Legal links sit in the bottom bar rather than a fifth
   column: it is where people look for them, and it keeps the four link
   columns evenly weighted.
