+/**
+ * The frontend plugin ABI (plan 03) — the contract + lifecycle machinery for
+ * dynamically-imported frontend plugin modules. See `types.ts` (the surface),
+ * `version.ts` (the handshake), `load-diff.ts` (pure decisions), and
+ * `driver.ts` (the effectful host). The composition root (src/app) wires the
+ * driver to the registry, the surfaces ports, and the plugin HTTP edge.
