   Сайт бухгалтерской компании — основные стили

   Палитра построена на корпоративных цветах: жёлтый, светло-голубой, синий,
   фиолетовый (ТЗ п.3).

   Распределение ролей и почему именно так:
     синий (#2a46c8)      — основной: кнопки, ссылки, акценты. Контраст с белым
                            7.5:1 — проходит WCAG AAA для обычного текста.
     фиолетовый (#6b35dd) — вторичный: второе направление услуг, градиенты.
                            Контраст с белым 7.5:1.
     светло-голубой       — ТОЛЬКО декоративный: фоны блоков, подложки иконок,
     (#7cc9f0)              градиенты. Контраст с белым 1.9:1, поэтому текстом
                            по белому он никогда не выводится.
     жёлтый (#ffc83d)     — акцент призыва к действию: фон кнопки с тёмным
                            текстом (контраст 11.4:1). Как цвет текста по белому
                            не используется — там он даёт 1.55:1.

   Светлая и тёмная темы описаны отдельными наборами токенов; тема
   переключается атрибутом data-theme на <html> и запоминается в localStorage.
