{{-- Facebook Pixel + Meta CAPI, GA4, Google Ads, GTM, TikTok, Custom.
     Each block only renders if the admin has switched it on in
     Admin > Tracking. Every event fires with a shared event_id passed to
     both the Pixel call (here) and our /api/track/event endpoint (server
     CAPI relay) so Meta can dedupe browser + server events. --}}
