1/**
2 * PWA Install Prompt Early Capture
3 *
4 * This script captures the beforeinstallprompt event BEFORE React hydration.
5 * It must be loaded synchronously (no async/defer) in the <head> to catch
6 * the event on mobile browsers where it fires early.
7 *
8 * The captured event is stored on window.__pwaInstallPromptEvent for the
9 * usePwaInstall React hook to consume.
