+- OTLP push target is configured in `config/features/telemetry.properties`
+- Prometheus scrape endpoint listens inside each node container on `http://0.0.0.0:9090/metrics`

 ## Configuration
 
 5-layer system — later layers override earlier ones. Each layer is a template rendered via `envsubst` before Docker starts. Final merged config: `.devkit/config/node-N.properties`.
