/*
 * Xakrom-Web · demo-cycle · style.css · v5
 * El ciclo en dos cajas, con el anillo de seis tramos, pensado primero para el móvil.
 * Solo lo propio del miniprograma: color, tipografía y geometría en ../_shared/tokens.css,
 * espejo de la app (WEB_Libro_Estilos). Sin colores literales y con pesos hasta 600.
 * Pliego: DEMO_Ciclo.
 * v5: fuera .btn--action, sin elemento desde que la pantalla final perdió el botón de la
 * lista de espera (D-035).
