/* ==========================================================================
   Minimalist Log in / Sign up styles — matches the site's dark ink / gold /
   Fraunces theme defined in _Layout.cshtml.
   Shared by: _AuthModal.cshtml, Login.cshtml (fallback), Register.cshtml (fallback)

   Reuses the layout's own CSS custom properties (--ink, --paper, --gold,
   --gold-soft, --line, --line-strong, --text, --text-dim, --font-display)
   when present, with fallback values here so the standalone fallback pages
   (which don't include the layout's <style> block) still render correctly
   on their own.
