   Визуальный язык
   - Режим: рабочий инструмент. Сначала понятно, где что лежит, потом характер.
   - Оболочка в своём цвете: тёмно-синяя навигация, светлая рабочая зона.
   - Один фирменный приём: схема линий. Уровень — линия своего цвета, миссии — станции,
     экзамен — пересадка. Приём живёт в маршруте, шагах миссии и прогрессе, а не в рамках.
   - Один шрифт: Onest (лежит в /fonts, лицензия OFL). Значки: Lucide.
   - Жёлтый — только «сейчас» и очки. Цвета линий — только уровни. */
