/* Havenga Fotos
 *
 * The photographs are the only decoration. Everything else is cool granite
 * graphite so the pictures hold the colour, with warm bone text over it — the
 * warm/cool tension is what keeps this from reading as a cold professional tool.
 * The single accent is vygie magenta, the flower that carpets the Namaqualand
 * veld these photographs come from. It appears only where something is selected,
 * focused or active; never as decoration.
 *
 * The year, set in a serif with old-style numerals, is the spine of the archive.
