1//! Tracing / telemetry configuration.
2//!
3//! The SDK emits structured [`tracing`] events for every request. OpenTelemetry export
4//! is available via the (optional) `otel` Cargo feature — kept behind a feature flag so
5//! default builds stay lean and language SDKs can opt in as needed.

10/// filter support. Safe to call multiple times (no-op after the first call).
11///
12/// Language SDKs are expected to call this at most once; for `PyO3` bindings this is
13/// invoked from the bridge's `Client.connect` implementation.
