THE TRAIL
The marker rides down the left gutter as you scroll — skiing, then biking, then hiking — and each waypoint lights up as you pass it.
01 — START
Placeholder section. Replace with real content — the trail only needs a data-wp marker to drop a node here.
02 — DESCENT
As the marker passes a third of the way down, it switches from skis to a mountain bike.
· a smaller waypoint
Mark any element with data-wp="minor" for a smaller node.
03 — RIDGELINE
Two-thirds down, the bike becomes hiking boots for the final push.
04 — SUMMIT
End of the trail. The whole line is lit and every node is filled.
