Decoded design system
On Running's decoded design system: background #FFFFFF, text #000000, accent #2F7EFE, link #2F7EFE, primary #ED0000; type scale h1 32.96px / h2 52.992px / body 32.96px; 4px spacing base; 4px base radius. The single interactive/action color is #FFFFFF — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.
