/* site/app/ui.css — the Apple interface layer, in The Rally Grounds' colours.

 * The components here are the iOS vocabulary: a large title that collapses into a compact

 * They are here because they are what people already know — familiarity is a design
 * principle, not a shortcut. A player who has used any iPhone app can already use this one.
