      1 # Tempo configuration for the distributed observability stack
      2 #
      3 # Receives traces over OTLP (gRPC 4317 / HTTP 4318) directly from the services
      4 # and is queried through Grafana at :3200 — Tempo has no UI of its own.
      5 #
      6 # Note: this targets Tempo v3.x, which replaced the v2 `ingester` and
      7 # `compactor` config blocks with a block-builder architecture. Those keys
      8 # are rejected outright by v3, so they are intentionally absent here.
