/* THE public top bar — ONE bar for every logged-out page.

   2026-07-22: the owner screenshotted five public pages and got five different
   banners — different nav items, different CTAs, four pages with no signup route
   at all, three separate CSS systems. This is the agreed design, taken from
   /analyses/latest: back pill, wordmark, section nav, Sign in + Create free
   account.

   Class prefix is `pubbar-`, NOT `tpx-topbar-`, deliberately: transcript_public.css
   and review_detail_v4.css still define the old `.tpx-topbar` rules and pages load
   them in varying order. A fresh namespace means this bar cannot be half-overridden
   by whichever sheet happens to come last.

   Self-contained: every token carries a fallback, so a page with its own palette
   can link this file without dragging in a design system. */
