/* ============================================================
   Shared shell for the homepage-family pages:
   index.html, index-en.html, work.html, work-en.html

   Extracted verbatim from index.html's inline <style>. The two
   homepages' stylesheets were byte-identical apart from one
   `content:` string, which is now the --preview-label custom
   property so a single file can serve both languages.

   NOT for the portfolio-pages.css family — the two stylesheets
   define .hero, .section, .nav-links and .tag* differently and
   must never be loaded together on one page.
