// PM2 processes for MSK Forms (concept §23).
// Deploy: `pm2 reload ecosystem.config.cjs --update-env`
//
// The standalone Next.js server (and the bot/realtime services) do NOT load
// `.env` themselves in production — Next only reads .env at build/dev time.
// So we load `/opt/msk-forms/.env` here and pass it through to every app's
// env. Node 22's process.loadEnvFile populates process.env without any extra
// dependency.
