   TEST DE CONVIVENCIA · estilos
   ---------------------------------------------------------------------------
   Todo lo de aquí empieza por .tc- y sólo afecta al test. No se cambia
   ninguna variable global ni ningún estilo del resto de la aplicación: se
   reutilizan las variables que ya existen en index.html (--brand,
   --brand-soft, --card, --line, --ink, --muted), así que el test queda
   automáticamente bien en modo claro y en modo oscuro.
