/* PDF Editor - layout & viewer internals.
 * Colors/typography come from the site's Tailwind tokens in the markup; this
 * file only covers what utilities can't express (virtualized viewer chrome,
 * thumbnails, dialogs, spinner). Theme-aware via the site's `.dark` class.
 *
 * NOTE: this stylesheet loads AFTER styles.css. Any rule here that sets
 * `display` on a class which is also toggled with Tailwind's `.hidden` MUST
 * use :where() (zero specificity) so `.hidden` always wins - same pattern as
 * the .material-symbols-outlined rule in partials/head.ejs. */
