/* =============================================================
   FB Phone Input — country flag picker + auto-formatted number.
   Used by every form across the site that captures a phone number.
   Markup contract: see assets/js/fb-phone-input.js docblock.

   v1.2.99: every `var()` carries a hardcoded fallback so the widget
   renders correctly in WP-admin context (where the theme's
   design-system.css tokens are NOT loaded). Without fallbacks the
   dropdown rendered transparent on admin pages.
