`main.go` only ever loaded `.env`; the `APP_ENV` switch described in `.env.local` / `.env.production` did not exist, and a missing variable surfaced one restart at a time as a log.Fatalf inside db.Connect. config.Load now picks `.env.<APP_ENV>` (default local) then `.env`, with real environment winning, reads every setting into one typed Config and reports everything missing in one message. Production insists on a POS signing secret; local warns when DB_HOST is not a local address. db, redis and the image store take the Config instead of reading env themselves. Also: - livehub read MQTT_USERNAME while everything else uses MQTT_USER, so the console stream connected to the broker unauthenticated. Both accepted. - .dockerignore: `COPY . .` was baking .env.production into the image. Dockerfile sets APP_ENV=production. - Drop utils/config.go (dead viper loader) and create_table.go (unused, hardcoded production DSN); go mod tidy removes viper. - .env.example lists every variable the code reads; docs/ENVIRONMENT.md.
