   _form.css — форма заявки на главной (.cf-*): 2-колоночный grid
   с тёмной preview-карточкой («Что будет дальше») слева и формой
   справа. На мобайле — одна колонка, preview сверху.

   Логика отправки в static/js/site_lead_form.js, разметка в
   partials/_lead_form.html. На всех публичных страницах сейчас.

   Зависит от _base.css (--font-serif, --bg, --bg-alt, --dark,
   --border, --accent-1, --accent-2, --muted, --faint).
