        Human views are counted in Mixpanel (``stamp.viewed``) — no client-side

        telemetry runs on the public page. The webapp renders it server-side, so the

        visitor''s user agent arrives as ``x-client-user-agent`` (this request''s own

        headers describe the Next.js server); a call without it is treated as

        automated and not counted. Nothing identifies the visitor, so this is a view

        tally only. The header is caller-controlled on an unauthenticated route, so

        treat the tally as inflatable — indicative, not audited.'
