/* tonus.css — стили для итерации 2.
 *
 * Минималистичный дизайн в духе спокойных продуктов: тёплый бежевый фон,
 * приглушённые цвета, серифный заголовок, sans-serif для прозы. Без анимаций,
 * без градиентов, без иконок. Финальный визуальный язык будет в отдельной
 * итерации — здесь задача в том, чтобы интерфейс не отвлекал.
