// Injected into every in-app WebView BEFORE page content loads, so the App
// Store binary performs NO ad/analytics tracking (App Privacy = "not used to
// track you", so no ATT prompt is required). The public website keeps its
// AdSense/analytics; only the native app is clean. (Reused verbatim from the
// Charge & Explore app — same Google ad/analytics script set to block.)
