Geometry reference stored on each entity. A single entity can own several
meshes (multi-material / multiple representation items), so this holds an
ordered list of pointers into the geometry top-level map (each == that
entry's geomId). Older docs stored a single geomId; readers fall back to
wrapping it as a one-element list.
