   Концепция: сайт как техническая документация на изделие.
   Принципы (по Anthropic frontend-design): distinctive выбор, привязанный
   к субъекту (производство фонтанного/металлооборудования), а не дефолт.
   ─ линия вместо тени   ─ малые радиусы (как у реальных деталей)
   ─ моноширинный = спецификация   ─ чертёжная сетка = signature
