/*
 * Дизайн-система мини-аппов Cashbird и BirdPay.
 * Принципы (см. packages/webapp/DESIGN.md):
 *  — цвета берём из темы Telegram (--tg-theme-*): светлая и тёмная тема пользователя;
 *  — бренд-цвет (--brand) один и только для акцентов: знак, график, активная вкладка, главная кнопка;
 *  — сгруппированные списки как в настройках Telegram, линейные иконки Lucide, без эмодзи;
 *  — деньги крупно и моноширинными цифрами; заголовки в обычном регистре; без градиентов и свечений.
