   Estilos del widget de LunaChat para la tienda Shopify.

   Todo vive bajo el selector "#lunachat-root" para no interferir con
   los estilos del tema de la tienda, y usa variables CSS para que la
   personalización de marca (color principal) sea trivial de cambiar
   desde JavaScript sin tocar este archivo.
