+//! Thin client wrapper for querying the indexer's JSON-RPC API in tests.
+//!
+//! The sequencer doesn't depend on the indexer at runtime — finalization comes
+//! from zone-sdk events. This wrapper exists purely for test ergonomics so
+//! integration tests can construct a single connection and call
+//! `indexer_service_rpc::RpcClient` methods directly via `Deref`.
