/* Login surface — Phase 15.4 (2026-05-18).
   Standalone (no app shell). Consumes:
     - _tokens.css      → color palette (--ink-navy, --surface-white, …)
     - _page_chrome.css → type + space + field tokens (--type-*, --space-*)
     - landing.css      → marketing tokens unique to the funnel
                          (--brand-deep, --gold-bright, --r-md, --font-serif)
   Intentional divergences kept as raw values: input height (42px is the
   marketing-comfort variant of --field-h-lg/40px), brand-deep focus ring
   (login picks up the marketing-CTA accent rather than the cool-steel
   --field-focus-ring), lowercase Inter Tight button label (not the
   uppercase --btn-* family used in-app). */
