/* ============================================================================
   reachtim.com

   Warm off-white page, dark warm ink for type, and very little else. The work —
   articles, photographs, drawings — supplies the colour; the page stays out of
   its way. Code samples are the one inversion, sitting as dark blocks on the
   light page.

   Accents are drawn from the art: a deep teal for the technical side, a deep
   ochre for the art side. Both are darkened well past their source values so
   that small text clears WCAG AA on this background.
