TrueRegPlate v1.0

Automatically displays the tractor’s license plate on any attached trailer or implement that has license plate nodes.
When you connect a trailer to Tractor A (e.g. DA24 HYT) the trailer’s plate visually changes to match. Detach it and connect to
Tractor B (DH67 JDT) and the plate switches to that registration.
The trailer’s own saved registration is never overwritten — only the visual display changes while attached. Saves and loads work correctly.
