/* /referrals — публичная страница с реф-ссылками на биржи.
   Стиль брокер-карточек TradingView (ru.tradingview.com/brokers):
   логотип + название + verified-галочка + градиентный бейдж (как PLATINUM),
   описание-«инструменты», копируемый реф-код, белая CTA «Зарегистрироваться»
   и тёмная вторичная кнопка. Сетка — 3 карточки в ряд. */
