1/* BetLegendPicks conversion events (Oct 1 2026).
2   Sends GA4 events through the page's existing gtag (G-QS8L5TDNLY). Safe when gtag
3   is missing or blocked: events are pushed to dataLayer and nothing else happens.
4
5   pro_cta_click      any element with data-pro-cta (the contextual Pro module)
6                      params: page_type, sport, source_url, cta_variant, destination
7   email_signup_view  an email form scrolled into view      (form[data-email-form])
8   email_signup_submit / email_signup_success / email_signup_error
9                      params: signup_source, list, page_type, sport, source_url
10   Links to the Pro checkout also carry utm_source=betlegendpicks so TrustMyRecord's
11   GA4 sees the arrival, checkout starts and purchases with the same campaign tags. */
