/* ==========================================================================
   CP CHAT - botón flotante pixel-art, burbuja de invitación y aviso de
   respaldo. El panel de conversación lo dibuja LiveConnect; esto es la capa de
   marca alrededor. z-index 900: por debajo del header (1000) y del carrito
   (2000+), por encima del contenido.

   Técnica (sin librerías ni imágenes): esquinas escalonadas con clip-path,
   borde = capa negra + capa interior inset, y volumen 3D con una "base"
   desplazada hacia abajo que se aplasta al presionar (botón de arcade).
