# OpenTelemetry (spec.telemetry.enabled: true)
# A2A_TELEMETRY_ENABLED is the ADK master switch: it turns on instrumentation and
# the telemetry server. The A2A_OTEL_* variables are the standard OpenTelemetry
# SDK settings read through the ADK's A2A_-prefixed config, so each OTEL_* name is
# emitted with the A2A_ prefix; every one maps 1:1 to a spec.telemetry field. A
# signal set to "none" is disabled; drop an OTLP endpoint/protocol to fall back to
# the SDK default. Auth headers, credentials, and sampling stay runtime concerns.
# W3C trace-context + baggage propagation is automatic.
