/* =========================================================================
   ПАСПОРТ ДИЗАЙНА — «Подпись пулемётом»
   -------------------------------------------------------------------------
   Главный факт: подпись наносится очередью — человек «стреляет» мышкой,
   а след от пуль становится его росписью под первой страницей договора.
   Структура: экран продукта (11) — первый экран показывает сам интерфейс
   тира, а не картинку; меню — липкая левая колонка-рейка (7).
   Ориентиры: Linear (точность интерфейса и сетка), Teenage Engineering
   (тёплая бумага + техническая типографика), Stripe (блок кода и понятные
   шаги), аркадные автоматы 80-х (трафаретные метки, счётчики).
   Палитра: бумага #F5EFE4, поверхность #FFFBF3, чернила #101216,
   терракота #C2542A, охра #E0A32E, сигнал #B7F03C.
   Шрифты: Unbounded (заголовки, кириллица), Onest (текст), системный моно
   для счётчиков и меток. Подключение — без блокировки рендера.
   Голос: коротко, по делу, с сухим армейским юмором; бренд никогда не
   говорит «инновационные решения» и не хвалит себя в превосходной степени.
   Движение: первая загрузка — появление рейки и карточки тира со сдвигом;
   при прокрутке — проявление секций; микрореакция — отдача кнопки тира.
   Запреты: без неоновых градиентов на кнопках, без кикеров над заголовками,
   без подписей «здесь будет фото», без стоковых улыбок.
