/* WD.1 (2026-06-05) — редизайн экрана входа через Claude Design (handoff bundle).
   Источник: Auth Screen.html. Грузится ТОЛЬКО из tasks/auth.html (per-page файл).
   Скоуп тем — body.auth-page, чтобы не задеть другие страницы.

   Локально доопределяем токены, которых нет в tokens.css (значения из
   colors_and_type.css дизайн-бандла — landing-extensions + системные шрифты).
   Намеренно НЕ трогаем глобальный tokens.css (это кросс-каттинг на все страницы). */
