/* =====================================================================
   Shared chrome for every public page (landing, pricing, book demo, signup,
   resources and the guides): design tokens, the sticky header and the footer.

   Loaded on all pages with <body class="public-page ...">, after
   landing-unicorn.css, so one header/footer definition applies everywhere and
   the pages cannot drift apart again.

   Tokens: light is the base set, dark overrides it. theme-init.js always sets
   html[data-theme] before paint, so there is no flash.
