+"""EnergiBridge: tiny canonical bridge for cross-domain interoperability.
+
+This module provides a minimal, production-friendly scaffolding that
+captures the essence of the EnergiBridge concept described in the MVP
+documentation. It is intentionally lightweight and does not change the
+existing runtime paths of the demo/tests. The goal is to offer a clean,
+extensible place for future adapters to map canonical DeltaForge primitives
+to vendor-agnostic representations and vice-versa.
