/**
 * Дашборд курса (Phase 4).
 *
 * Структура:
 *   .dashboard-page     — корневой контейнер с radial-gradient в верхней части
 *   .dashboard-content  — центрированный контент max-width 920px
 *   .dashboard-hero     — «Продолжай отсюда» / «Курс завершён» (data-state)
 *   .dashboard-sheets   — 3 шпаргалки (data-locked="true" если курс не завершён)
 *   .dashboard-modules  — список модулей с тремя состояниями (data-state)
 *   .dashboard-foot     — ссылка «Успешные встречи» + контакты
 *
 * Состояния модуля:
 *   data-state="done"     — пройден (border-left success, иконка check-circle)
 *   data-state="current"  — текущий (border-left accent, фон elevated, прогресс)
 *   data-state="locked"   — заблокирован (opacity 0.55, иконка lock)
 *
 * Hero состояния:
 *   data-state="in-progress" — meta + title + desc + progress + кнопка «Продолжить»
 *   data-state="completed"   — иконка trophy в акценте + статистика + CTA «Открыть шпаргалки»
 *
 * Зависимости: design-system.css (CSS-переменные акцента, темы, semantic).
