            Тариф ищется по порядку: <strong>персональный тариф ученика в группе</strong> →
            <strong>индивидуальный</strong> (для мини-группы) или <strong>общий</strong> тариф
            в карточке ученика → <strong>тариф группы</strong>. Если ни один из них не найден
            (или указанный тариф был удалён), ученик попадает в этот список.

                             this app's own `data-theme`, never Bootstrap's
                             `data-bs-theme`, so the -subtle backgrounds stayed light
                             in dark mode (see 082ea56, which fixed the same mistake
                             on the teacher dashboard). It now carries both, so
                             -subtle would work; the solid badges are kept because
                             they're what every other view here uses. --}}
