	clip.hpp
	Polygon booleans and offsets on integer nanometres, a thin wrapper over Clipper2 (Angus Johnson, 2022; the Vatti scan-beam clipper, 1992).
	point.hpp
	Integer-nanometre points and KiCad-compatible rotation.
	poly_index.hpp
	Bucketed edges of one large closed polygon (a zone fill), so "does this disk touch the polygon?" costs the edges near the disk instead of every edge.
	shape.hpp
	Exact integer geometry for clearance checks (design doc 03 §1).
