"""Demo: EnergiBridge Interop Sketch (Non-breaking, MVP-friendly).

This tiny script demonstrates how core NovaPlan primitives can be mapped
to a canonical representation via EnergiBridge, and how a simple CaC contract
artifact can be registered for governance/provenance. It is intentionally small
and side-effect free for unit-test safety, but serves as a concrete demonstration
for developers extending adapters and contracts.
