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.

Framework guidelines

For Next.js 15.3+, initialize PostHog in instrumentation-client.ts for the simplest setup
