and runs during HTML parse, but hubspotutk is set by
js.hs-analytics.net, measured loading at ~834ms. On a first visit the cookie
does not exist yet, so a single read returns nothing and the visitor gets no
external ID at all — and a first visit is exactly what an ad click is. So
poll briefly until HubSpot sets it. The SDK loads lazily (~4.5s) and replays
a queue, so an init queued a second or two in still lands before any events
are transmitted. */

sign of real user intent. No preconnect on purpose — a TLS handshake during

3. Conversion id
sha256(lowercase(email) + "|" + formId + "|" + ISO-hour), first 20 hex,
"lead_" prefix.
- email lowercased/trimmed so casing does not fork the id
- formId keeps two different forms in the same hour from colliding
- the hour bucket is only the server's fallback; the id computed here is
sent to the relay verbatim, so the two paths cannot disagree even when
a submit straddles an hour boundary
Ads Manager's own sample omits event_id. We send it so the pixel event and
the relay event collapse into one conversion instead of counting twice.
