// Идея компонента: полоса показывает срок, но не отвечает на вопрос
// «успеваем ли». Готовность рисуется заливкой ВНУТРИ полосы, а ожидаемая
// на сегодня доля — засечкой на той же полосе: отставание видно как разрыв
// между заливкой и засечкой, без второй строки «план/факт». Проценты
// продублированы числом: по длине заливки 55% от 70% не отличить.
