   Подсмотрено у репетитора — кандидат новой главной · V3_FINAL (owner micro-polish)
   LOCAL_DESIGN_PROTOTYPE_ONLY. Палитра и типографика — из production css/styles.css.
   V3_FINAL = ровно 3 микроправки к принятому по архитектуре V3:
     1) brand-block: меньше вертикального разрыва имя ↔ знак/tagline — единый lockup;
     2) mobile hero: сокращены вертикальные margins/gaps H1→LEAD→формула→CTA (шрифты и порядок не тронуты);
     3) transition-text: serif → основной sans интерфейса (мост, а не литературная цитата).
   Тексты, архитектура, фото, ассеты, цвета — не тронуты.
