/**
 * AlpineConsent — public loader. Granular category consent, persisted,
 * Shadow-DOM isolated, themeable via --alpine-* props (docs/TECHNICAL.md).
 * Prior-blocks data-category scripts/iframes (incl. late-injected) and
 * signals Google Consent Mode v2. Layout/text/buttons/en-de language
 * read from window.AlpineConsentConfig when present (WordPress plugin's
 * class-loader.php), else fall back to the defaults below. NOT yet
 * included: theme-matching the host site, languages beyond en/de.
 *
 * Canonical source — wordpress-plugin/assets/js/alpineconsent.js should
