+- При создании сайта с `issue_ssl: true` автоматически выпускается сертификат
+- `POST /api/v1/sites/{id}/ssl/issue` — повторный выпуск
+- `GET /.well-known/acme-challenge/{token}` — HTTP-01 challenge
+
+Требования для SSL:
+- `ACME_EMAIL` в `.env`
+- DNS домена указывает на IP сервера
+- Порт 80 доступен для HTTP-01 (nginx → webroot или панель)
