 * Newsletter PDF viewer modal.

 * Its own stylesheet rather than part of pages/newsletters.css, because the
 * modal is used in two places — the archive and a single issue — and that
 * file only loads on the archive. Living there left the modal unstyled on an
 * issue page.
 *
 * Markup is template-parts/newsletters/viewer-modal.php; behaviour is
 * assets/js/newsletters.js.

 * Same fixed-overlay + fade/scale-in pattern as the sponsorship
