referer is the ?referer= param on this page's URL (a UTM-like ad tag). The SDK reads it and posts it in session.start.props.referer — only when present. It is not the HTTP Referer header and is not part of context.

Separately, the server derives this context on every event (the /collect response has no body, so this is what the server sees):
| ip | |
| user_agent | |
| origin |
Plus server-generated: event_uid, received_at, guest_id / user_id.
Pulls live state from GET /stats (admin-only, needs the metrics token) — buffer depth, Redis status, and the latest events exactly as stored in Redis, fully enriched by the server (event_uid, guest_id, context…).
