   Guestlist — shared foundation for the static public pages.

   Linked BEFORE each page's inline <style>, so page-local rules
   always win on a tie. Put tokens + cross-page primitives here;
   leave layout and page-specific components in the page.

   Bump the ?v= query in each <link> when this file changes —
   firebase.json sets no Cache-Control for CSS, so a deploy can
   otherwise serve a stale base.css against fresh HTML.
