/* centennialdig.com — "The Spark" identity.
 *
 * Built from the DIG wordmark: heavy black letters, one chartreuse burst. The
 * whole system is that split. Everything is disciplined and professional except
 * a single green flash of insight, which is also a fair description of a
 * student consultancy doing real client work.
 *
 * #D4DF38 is Centennial's own green, measured from centennialcollege.ca, and
 * the DIG logo has carried it from the start. It never carries text: ink sits
 * on it, it sits behind. One spark per surface.
 *
 * Archivo Black doubles as the wordmark face, so the logo and the headlines are
 * literally one voice. No Inter, Sora or Plex — those belong to the other
 * properties.
