/*!
 * Journal site theme — stylesheet
 *
 * Classic journal layout: utility bar, logo + title + Open Access / ISSN / QR header, a full-width coloured
 * menu bar with drop-downs and a search box, a 755px content column with a 196px widget column on the
 * right, tabbed article lists and a footer. All colours come from the journal's own theme settings.
 *
 * Self-contained: no Tailwind / Vite dependency, so the theme works the moment the files are deployed.
 * Per-journal colours arrive as CSS custom properties injected by the page layout (--m2-brand, --m2-nav-bg,
 * --m2-top-bg, --m2-foot-bg ... all derived from the journal's theme settings).
 *
 * Contents
 *   1. Tokens & base            6. Article lists, tags, issue header, archive
 *   2. Top bar & language       7. Content blocks: prose, forms, tables, notices
 *   3. Header, logo, OA, QR     8. Article page
 *   4. Menu bar & drop-downs    9. Footer, floating UI, modals
 *   5. Page layout, widgets    10. Responsive & print
