##
## OpenTelemetry Collector config for Dolphin.
## Receives OTLP from NG* machines (remote eigenvalue scanner, future services).
## Writes to dolphin ClickHouse — otel_logs / otel_traces / otel_metrics tables.
##
## OTLP endpoints:
##   gRPC  :4317   — for OTel SDKs (NG* machines via Tailscale)
##   HTTP  :4318   — for curl testing / http SDK
