/* ============================================================
   Окно авторизации: вход, регистрация, подтверждение почты,
   сброс пароля (accounts/auth_system/authentication_n_authorization.html).

   Макета в Figma нет — окно собрано в стиле новых страниц сайта и
   личного кабинета (accounts/css/cabinet.css): тёплая палитра, шрифт
   Hanken Grotesk, коралловый #E25C42 на действиях и при наведении
   на интерактивные иконки, мягкое торможение в анимациях.

   Ширины — по .memory-bank/ui-rules.md, как у кабинета: Desktop и
   Tablet — окно по центру, Mobile (до 767px) — шторка снизу.

   html в base.css имеет font-size 8.5px, поэтому размеры здесь в px.
