/* ================================================================
   REZVIVO — спортивный дизайн
   ----------------------------------------------------------------
   Концепция: тёмный энергичный лендинг, светлая внутренняя часть.
   Палитра бренда: navy (#0d3b6e) и cyan-молния (#3eb8e8) с логотипа.
   Геометрические паттерны напоминают трек / контурные линии велогонок.

   Шрифты: системные стеки (без внешних зависимостей).
