/*
 * Race UI.
 *
 * The world this sits on top of is light, chunky and toy-like, so the interface
 * is built as crisp white cards rather than the dark translucent HUD most
 * racing games default to: it reads as the scoreboard clipped to a slot-car
 * set, which is what the game actually is.
 *
 * One typeface, one accent, hairline borders, hierarchy from weight and space.
 * The accent appears only on the primary action, the active state, and the
 * start lights.
