// Command cepis-telegram is the official Telegram bot for https://cep.is.
//
// It answers a bare CEP in a private chat, "/cep <cep>" in groups and channels,
// and inline queries anywhere. Updates arrive by long polling, so the process
// needs no inbound port, no public hostname and no webhook secret.
//
// Configuration is environment-only; see the config package.
