/* Paper2Quote landing — shared design tokens + base styles + nav + footer.
   Phase 1 of the 0.3.0 landing rework: extracted from the duplicated <style>
   blocks in index.html / main_page.html / changelog.html and the duplicated
   `globalCss` template literals in login_page.html / register_page.html /
   user_dashboard.html / admin_dashboard.html.

   Token values match the vanilla landing pages (index/main_page/changelog).
   The four React-CDN pages were drifting slightly (--muted: #516377) and are
   re-aligned here on the canonical vanilla values (--muted: #5a6e82).

   Phase 2 evolves these tokens + selectors toward the desktop app's Ds visual
   language. */
