Detailed Description

Incremental side-level contour extraction and boundary-loop tracing.

Boundary primitives are oriented grid edges. Edges are materialized lazily per node, then traced into ordered loops on demand. The orientation convention keeps the support pixel on the right side of each directed edge in image coordinates, where rows grow downward and columns grow rightward. With this convention, external loops have positive doubled signed area and internal loops have negative doubled signed area.
