/* ============================================================
   iv-chat.css — presentacion del CHAT WEB embebible (V1).

   Mismo sistema que iv-directory.css: todo el tema deriva de
   --iv-accent (configurable por el negocio) + variables claro/
   oscuro; el movimiento vive integramente aqui (el JS solo pone y
   quita clases) y se apaga completo con prefers-reduced-motion.
   Mobile-first: en pantallas <=480px el panel ocupa el ancho de la
   pantalla con margenes dignos.
