<?php
// ── Botlify Cloud .env — auto-injected, never hardcode secrets ──
$BOT_TOKEN     = getenv('BOT_TOKEN');     // Telegram bot token from @BotFather

Botlify Cloud Runtime
Credentials are auto-injected in .env — always load them with getenv(): BOT_TOKEN, ADMIN_CHAT_ID, BOT_USERNAME. Main database: database.db (SQLite, WAL mode). Runtime errors: error.log. Quick test: send to $ADMIN_CHAT_ID. Full details: Runtime Reference.
