//! OpenTelemetry foundations for crawlberg.
//!
//! Three sub-modules:
//!
//! - [`attributes`] — re-exports upstream semconv constants plus `crawl.*`
//!   extension keys.
//! - [`metrics`] — process-wide [`MetricRegistry`] singleton (Cluster 2
//!   populates it with instrument handles).
//! - [`init`] — `with_traceparent` / `current_traceparent` (always compiled)
//!   and the optional `init_otlp` helper (requires `telemetry-init` feature).
