/* Shared look for every page except the homepage (static/home/a.html, b.html).
   The homepage split test shows design "a" (light) or "b" (dark) and keeps the
   choice in the wd_home cookie; each page's first <script> copies it to
   <html data-theme>, so the rest of the site matches the homepage a visitor saw.
   Without the cookie (or without JavaScript) a page shows "a".

   The tokens keep the names the pages already used (--bg-primary, --accent, ...),
   so a page's own component styles work in both themes. When the test ends,
   delete the losing theme's block. */
