/*
 * Phase C31: Guided Tours overlay styles.
 *
 * All values use --closina-* CSS tokens (Cat 22).
 * Z-index uses var(--closina-z-modal) so the overlay sits above the app shell
 * but below tooltips (--closina-z-tooltip).
 * Dark mode is handled automatically via token values under [data-theme="dark"].
