• Langfuse UI (Credentials: user@odctl.io / password):
  - External (host): http://127.0.0.1:3005
  - Internal (Docker): http://langfuse-web:3000
• OTLP endpoint for traces, over HTTP:
  - External (host): http://127.0.0.1:3005/api/public/otel
  - Internal (Docker): http://langfuse-web:3000/api/public/otel
• Project keys: public key pk-lf-odctl, secret key sk-lf-odctl, sent as
  HTTP Basic auth. Send the header x-langfuse-ingestion-version: 4 so
  Langfuse shows a trace at once, not up to 10 minutes later.
• Starts ch-lite, so it cannot run beside ch-full.
