   TES-WEB · PUBLIC ANNOUNCEMENT VIEWER  (assets/css/announcement-viewer.css)
   --------------------------------------------------------------------------
   The pop-up the landing-page carousel opens: the SAME two-pane photo viewer
   the portal uses (markup: includes/render_announcement_detail.php,
   behaviour: assets/js/announcement-detail.js). These rules are copied from
   the viewer section of portal.css so the landing page doesn't have to load
   the whole portal stylesheet; if the portal viewer's look changes, mirror
   it here. Public-only extras (sign-in box, page scroll lock, button resets
   the landing page lacks) are at the bottom.
   Loaded after index.css, which brings in tokens.css (colours, dark mode).
