   Направление «Помни Всегда — Камень» /stone
   Свой layout (Pages/Stone/_StoneLayout.cshtml): core.css и бандлы основного сайта сюда НЕ подключаются,
   поэтому здесь и сброс, и база. Префикс классов — st-. Mobile-first.
   Дизайн — как у страниц памятников основного сайта (core.css, granitnye-pamjatniki.css): те же цвета
   (--green-700 #1F6B36, --green-50 #EEF5EA, фон #FAF9F7), карточки 16px, кнопки 12px, отступы секций 56px,
   заголовки Lora 600 (CLAUDE.md «Шрифт заголовков»), текст Manrope. Тон — светлый, спокойный, интерьерный.
