   site-chrome.css — RackCity marketing chrome (www host)

   THE single source of truth for the global header + footer and
   the shared brand tokens (colors + Sora font) they ride on.

   Loaded via a plain <link> on every marketing page (landing,
   base_article and everything that extends it, terms, privacy),
   BEFORE each page's own inline <style>. It owns only the SHARED
   identity tokens + the nav and footer rules; page-specific tokens
   (--spacing-section, --radius-*, --shadow-card, form placeholder)
   stay in each page's own :root.

   Markup lives in templates/partials/_header.html + _footer.html.
