+ * Resources section) asks this registry for a gateway and gets either the
+ * one implementation a plugin registered, or null. Null is the honest
+ * "no plugin installed" state — callers branch on it.
+ *
+ * v1 assumes a single provider (PgmPro). If a second plugin ever registers
+ * a gateway on the same install, the first registration wins and the second
+ * is logged. That's a conservative default — silently letting a second
+ * plugin overwrite the first would cause a data-source ambiguity nobody
+ * would notice until reports started disagreeing.
