  Smond Design Kit -- shared web stylesheet.

  Structural/component CSS for Smond marketing sites (landing pages, support,
  privacy/legal pages). Always beige/paper-and-ink -- unlike native apps, web
  properties don't switch to a platform-native mode. Load ../tokens/tokens.css
  first (or @import it, as below), then this file, then any page-specific CSS.

  Extracted from the Single Screen site (singlescreen.app) -- built generic
  from day one, so this is close to a straight lift. Class names are
  unprefixed (.nav, .hero, .feature, ...) since this is meant to be the only
  sitewide stylesheet for a given project, not one library among several.
