   El aviso era una línea de texto y se pidió que se notara más. Sube a
   tarjeta con tres alturas de lectura: el rótulo, quién ganó y —lo
   grande— qué ganó. El contenido lo arma chat-widget.js desde
   `cha_params`; aquí solo se maqueta.

   Los colores van en este archivo en su versión legacy (rosa fijo) y se
   redefinen por token en nw-ui/components.css, como el resto del chat.
