   dregg explorer — cells, turns, receipt chains.

   The `:root` token block below is lifted verbatim from this
   directory's `style.css` (the surviving stylesheet of the old
   explorer) so the surface keeps the established visual language.
   Everything else is new: `style.css` is a 1964-line app-shell for
   a component platform that no longer exists, and it @imports a
   remote font, which a verification page must not depend on.
