/* GoldTrack Australia
 *
 * Designed for a phone held at arm's length in bright sun, by someone wearing
 * gloves. That drives most of what follows: large tap targets, high contrast,
 * no thin grey-on-grey text, and colour never used as the only signal — every
 * status carries a word as well as a hue.
 *
 * Palette is quartz reef and ironstone rather than the obvious gold gradient:
 * pale quartz, oxidised red, and the deep brown of weathered ore. Gold itself
 * is used once, on the score, so it means something when it appears.
