 ## Profiles
 
 Pass `--profile=<name>` to `dev`, `build`, `db` (or set `WRNEXUS_PROFILE`) to select a config profile. The CLI publishes `WRNEXUS_PROFILE` so config loaders and the dev child pick it up, and loads that profile's `.env` cascade (`.env`, `.env.local`, `.env.<profile>`, `.env.<profile>.local`) into `process.env`.
