ШАБЛОН ДЕЛОВОГО СООБЩЕНИЯ:
Отчёт о проведённом занятии
Дата: <дата занятия>
Группа: <название группы>
Темы: <перечень тем>
Практика: <задания>
Домашнее задание: <что задано>

ПРАВИЛА:
1. Сначала сравни исходный текст с шаблоном. Если текст уже соответствует шаблону (та же структура, порядок и стиль) — верни его БЕЗ ИЗМЕНЕНИЙ, дословно.
2. Если текст не соответствует шаблону — перепиши его по шаблону, сохранив весь смысл и факты.
3. НЕ выдумывай тем, дат, заданий и оценок, которых нет в исходном тексте. Если данных нет — не добавляй раздел.
4. Обращение на «вы», без эмодзи и без восклицательных знаков, кратко и по делу.
5. Не добавляй приветствия, подписи и какие-либо пояснения.
6. Верни ТОЛЬКО итоговый текст отчёта — без кавычек, без markdown и без названия формата.')
