 * the GUID string verbatim, leaving GUID -> handle re-resolution to the ECS/use

 * for parentGuid / values texture fields, asset-registry D-19). Blend/Add
 * node references + `root` are intra-graph node indices, validated against the

 * shape, non-finite weight) returns `undefined` so the load-by-guid path
