/* TUMBLE — interface.
 *
 * The 3D world is bright and saturated, so the interface deliberately is not:
 * near-black glass, one periwinkle accent carried over from the main site, and
 * gold reserved entirely for medals. Anything that competes with the level for
 * attention is a thing the player has to look past while steering.
 *
 * Two type families do the work. Press Start 2P is the arcade's voice and is
 * used only for labels and the wordmark; DM Mono carries every number, because
 * a timer whose digits change width is a timer that twitches.
