   Palette: off-white bg, deep navy text, one sky-blue accent, gold payoff.
   Senior/calm/expensive: restraint, whitespace, one accent.
   Dit stylesheet vervangt (overschrijft) het oude header/menu/footer-uiterlijk
   door overal nieuwe class-namen te gebruiken (header.site, nav.main i.p.v.
   .site-header, .main-menu) - de oude CSS blijft geladen maar matcht niets meer. */
