   la variable --iti-country-selector-bg; el texto (nombres de país) se HEREDA del

   CUALQUIER modo: inline (desktop) y fullscreen (mobile, que la librería monta en
   <body>, fuera de .contact-form-card). Las clases .iti__* solo existen en la página
   de contacto, así que poner las variables en :root es inocuo en el resto del sitio.
   Sin !important, sin tocar fondos/overflow internos: solo las palancas oficiales.
   Usamos `html:root` (no `:root`) a propósito: el CSS de la librería se enlaza
   DESPUÉS de este archivo y define `:root{--iti-country-selector-bg:white}` con la
   misma especificidad, así que ganaría por orden. `html:root` tiene un punto más de
   especificidad → nuestras variables ganan SIEMPRE, sin depender del orden de <link>
