+`projectedConnectionPaintOverflow` adds conservative scene-space bounds for cubic
+control hulls plus half stroke. It uses the same geometry protocol and connector
+adapters as hit testing, with native handles for custom record renderers. Default
+work limits are 4096 edges and 4096 total cubic segments. Missing geometry,
+invalid values and exhausted budgets remain unknown and suspend native culling;
+they are not treated as empty paint. CanvasView queries a separate overflow grid
+against its viewport. This currently retains the whole view when needed; it is
+not selective edge mounting, exact curve bounds, overlay indexing or dirty-region
+rendering. Custom renderers must supply a compatible geometry protocol.
