/*
 * Expeio marketing site.
 *
 * Light, quiet, typography-led. The restraint is the point: one ink colour, one
 * accent, hairline rules, and a lot of white. Lime is load-bearing only on the
 * primary button and a couple of accent marks - spend it anywhere else and it
 * stops meaning "act here".
 *
 * Lime never carries text on white (it fails contrast badly). Where lime is a
 * fill, the text on it is always the deep green ink.
