/* ---------------------------------------------------------------------------
 * Four skins, four applications. The markup never changes; each theme rebuilds
 * the shell out of it, so the palette is only the first thing that differs.
 *
 *   red     Glass and covers. Frosted sidebar, a scrolling rail of big artwork,
 *           soft spring motion. The default.
 *   green   A panelled desk. Rounded black slabs with a gutter between them,
 *           two-up shortcut tiles, numbered track lists, sharp motion.
 *   amoled  A printed index. Pure black, hairlines, station rows numbered like
 *           a contents page. The index stays grayscale; the playing cover does not.
 *   rainbow A living aurora. Drifting colour behind glass chips, every station
 *           tinted its own hue, bouncy overshoot on absolutely everything.
