/* ============================================================
   The welcome (assets/welcome.js): a full-screen Big Sky. The sky fades from dawn to day as you go, the sun
   climbs, clouds drift, and three ridges of the range glide past at their own depths with every step, while
   a little Bo walks the trail at the top. Each scene draws its own small story (a trail climbing to the exam,
   a quiz answered, Bo writing on his board, a syllabus turning into a class). The choices are big pressable
   cards on the sky. Nothing moves when motion is off or reduced: every animation starts from its first frame
   and rests on the final look, which is the static style.
