 * Three per-character waypoints where the robot pauses to scan.
 * Coordinates are tuned against the painterly island PNGs (1376x768),
 * placing the robot on the walkable top surface — never below ~Y=58%
 * (the painted "floor" ends there on every island) and never narrower
 * than ~X=28% / wider than ~X=72% (the rocky base under-cuts the land
 * past those bounds).
 *
 * If a point looks off, prefer adjusting yPct first; the surface plane
 * (where things "stand") sits well above the geometric center of the
 * floating mass.
