"""Logger configuration for Langfuse OpenTelemetry integration.

This module initializes and configures loggers used by the Langfuse OpenTelemetry integration.
It sets up the main 'langfuse' logger and configures the httpx logger to reduce noise.

Log levels used throughout Langfuse:
- DEBUG: Detailed tracing information useful for development and diagnostics
- INFO: Normal operational information confirming expected behavior
- WARNING: Indication of potential issues that don't prevent operation
- ERROR: Errors that prevent specific operations but allow continued execution
- CRITICAL: Critical errors that may prevent further operation
"""
