/* BallRoute website.
   Look: a puzzle-book page — warm graph paper, ink-navy type, the app's mint
   and gold, hand-written notes, hard offset shadows. The phone in the hero
   keeps the app's own palette (--app-*), so the demo looks exactly like the
   game. Dark mode follows the system unless the visitor picks one. */
