/* AAMUC Auth Design System — the standalone sign-in experience (and any future standalone auth
   screen: password reset, pending-approval notice, etc.) shares this file rather than re-inlining
   a one-off <style> block per page. Built on top of the app-wide tokens in tokens.css (brand-navy/
   brand-red/focus-ring/etc.) — no parallel token system, this only adds the handful of values a
   full-bleed branded auth page needs that an in-app portal page never does (radial glow stops,
   card elevation). Every color reachable from here traces back to a token, so a future brand
   color change (BrandingSettings.PrimaryColor/SecondaryColor) still flows straight to this page
   via the inline custom-property overrides LogIn.cshtml sets on :root. */
