+// Grippable + PropertyEditable for Solid3D, Region, Body.
+//
+// Geometry lives in ACIS data — we cannot edit it via the properties panel.
+// We expose the point_of_reference as a translate grip and show ACIS size
+// as read-only info.  Grip translate also updates wire points so the wire
+// fallback stays in sync; the caller (scene/mod.rs apply_grip) translates
+// the MeshModel vertices to match.
