/*
 * Notification + loading UI (toasts, confirm dialog, blocking overlay, page
 * progress bar).
 *
 * Written as plain CSS on purpose:
 *  - it lives in public/, which Tailwind does not scan, so utility classes used
 *    from JS would be purged out of the build;
 *  - the layouts fall back to the Tailwind Play CDN when no Vite build exists,
 *    and this file is linked in both paths.
 *
 * Colours come from the design tokens in assets/portofolio/theme.css, so dark
 * mode follows the rest of the app with no extra work.
