The bound layer's OWN marker points, when it carries any.
🛑 This is the only way an intermediate stop can exist. Nothing in a LineString says which of
its vertices are stops, so a via is never derived — it is read from data that already says so.
A layer with no roled points answers an empty list, and the caller derives instead.
