/* ============================================================================
   LIF Trainer Lab — estilos

   Usa tokens globales del dashboard (--primary, --accent, --text, --line,
   --surface, --radius, etc.). Agrega tres tokens semánticos propios solo
   para los colores de acción de poker (Fold/Call/Raise/All-in), que son
   semántica específica del dominio.
