   DESIGN PASSPORT
   niche:    кухни на заказ, Нижний Новгород («Графит и Дуб»)
   palette:  тёмная Black & Tan: графит #16130f / #1e1a15, светлый текст
             #f2ede4, акцент тёплый дуб/тан #d29a5b. Один акцент на страницу.
   fonts:    одна семья Golos Text (variable 400..800, self-hosted woff2):
             жирный дисплей 800 + текст 400/500.
   radius:   всё острое, radius 0 везде (столярная геометрия). Исключений нет.
   hero:     full-bleed фото со скримом, текст поверх, город в нижнем углу.
   devices:  крупные номера этапов на полях, галерея работ с картами разного
             размера (12-колоночная сетка 7/5, 6/6, 5/7), линейки 1px как
             разделители в отзывах и контактах.
   sections: hero, работы (кейсы с фактами), материалы, квиз (4 шага + вилка
             цены), этапы, производство, отзывы (крупная цитата + 2 малые),
             контакты + форма, футер.
   --------------------------------------------------------------------------
   Фото живут в assets/img (jpg). Контейнеры держат aspect-ratio,
   картинки object-fit: cover.
