- Add HTTP OTLP exporter (opentelemetry-otlp 0.31) via SdkTracerProvider + BatchSpanProcessor + tracing_opentelemetry layer - Add Prometheus /metrics handler via metrics-exporter-prometheus 0.13 - Replace slog with tracing throughout: HttpMetrics, TracingSpanMiddleware - Replace .init() with .try_init() to allow OTLP layer registration after init_tracing_subscriber() - otlp.rs: SpanExporter::builder().with_http().with_endpoint(), Resource::builder().with_service_name(), .with_attribute(KeyValue::new(...)) - prometheus_exporter.rs: install_recorder(), prometheus_handler(), spawn_http_metrics_poller()

//! Observability primitives: tracing subscriber, metrics, OTLP export.

//!

//! Call `observability::init_tracing_subscriber(level)` once at startup.
|
|
//! All services then use `tracing::info!`, `tracing::warn!`, etc. directly.
