/**
 * hwc-quicksight – print.css (loaded with media="print")
 *
 * Fits the embedded QuickSight dashboard to the printed page width.
 *
 * The iframe is kept at the size it has on screen (so QuickSight does not
 * re-render) and scaled down with transform: scale(). CSS `zoom` cannot be
 * used: browsers ignore it inside cross-origin iframes when printing, which
 * crops the right-hand side of the dashboard.
 *
 * The on-screen iframe size is published by assets/js/print-fit.js as the
 * custom properties --hwc-qs-w / --hwc-qs-h (unitless px) on
 * `.hwc-qs-print-host`.
 *
 * Page size and margins (@page) are handled by the theme stylesheet.
