/*
 * Trader space: the frame (side navigation, top bar, tabs on a phone), the page heading and the overview strip.
 * Same family as the terminal and the brand site: bluish graphite, the brand accent, green and red only for direction,
 * amber at the limits. Colours, radii and motion are the tokens of ../style.css; nothing is hard-coded here.
 * Hover effects live under (hover: hover) so that a first tap on a phone is never swallowed.
