Waypoint lock route

Variant: Linear

The same three-marker route confirmation, but every curve is linear: markers drop at constant speed and the path draws at a steady rate. Use it when the widget reads as instrumentation — a tracker or telemetry panel — where an even pace implies measurement rather than personality. Linear removes the sense of arrival, so the halo at the end carries all of the emphasis.
