 * AsereFlights booking widget.
 *
 * Mobile-first and self-contained: everything is scoped under .asf-booking and sets its own box-sizing,
 * colours and control styling, because a WordPress theme's resets are unknowable. Sizes are in rem so the
 * widget follows the theme's base font, and tap targets stay at least 44px on touch.
 */

/*
 * Tokens live on both the widget and the modal overlay: the dialog is appended to <body> (so `position:
 * fixed` can't be trapped by a transformed ancestor), which puts it outside .asf-booking — where these
 * variables would otherwise be undefined, leaving it transparent and unstyled.
