Key principles

• Environment variables: Always use environment variables for PostHog keys and OpenTelemetry endpoints. Never hardcode them.
• Minimal changes: Add log export alongside existing logging. Don't replace or restructure existing logging code.
• OpenTelemetry: PostHog logs use the OpenTelemetry protocol. Configure an OTLP exporter pointed at PostHog's ingest endpoint.
• Structured logging: Prefer structured log formats with key-value properties over plain text messages.
