 * Дизайн-система InterviewMode: тёмный «приборный» интерфейс в духе Linear.
 * Поверхности различаются тоном и тонкой границей, а не тенями; Inter с плотным трекингом;
 * один хроматический акцент (лайм) — только на главном действии экрана и активных индикаторах.
 * Радиусы: 12px карточки, 6px кнопки и поля, 4px бейджи, pill — чипы.
