Hit shape in overlay-local CSS pixels (rev4 §A4). native overlays render these as SVG clip primitives (browser hit-testing follows the shapes); proxy overlays point-test them before forwarding packets. Absent shapes mean the whole rect is interactive. Caps: limits.overlays.maxShapes, maxPolygonPoints, maxGeometryBytes.
