/**
 * cifras-home.css
 * Hoja de estilos propia y nueva para el rediseño del home de Cifras.
 * No toca css/home.css ni css/styles.css (compartidos por el resto del
 * sitio) — todo aquí vive bajo el espacio de nombres .cf-home / .cf-*
 * para que el resto de páginas, que aún usan el diseño anterior, no
 * se vean afectadas hasta que les llegue su turno.
 *
 * Requiere assets/brand/tokens/cifras-ss-ui.css cargado antes (define
 * las variables --ss-color-*, --cf-*, --ss-font-*, --ss-radius-*).
