   Layout: a sticky header; on wide screens it carries a tab bar, on phones and
   tablets a Menu button that opens the same tabs as a list. Each tab is its own
   page in a single 1120px column, opened by a large Garamond title. One navy
   band on Home carries the key figures.
   Rules are written phone-first; min-width queries add the wide-screen layout. */
