/* DBN VAULT storefront — switchable themes.
   Presentation is driven entirely by CSS variables. The active theme is the
   data-theme attribute on <html>, set pre-paint by the inline script in
   base.html (localStorage 'dbn_theme', cookie fallback) and changed live by
   static/js/theme.js via the header switcher.
