-## Exit Codes
-
-The application uses the following exit codes for process termination:
-
-| Code | Meaning | Trigger |
-|------|---------|---------|
-| `0` | Success / Graceful shutdown | `SIGTERM`, `SIGINT` signals |
-| `1` | Runtime error | Uncaught exceptions or unhandled promise rejections |
-| `2` | Cleanup error | Error during graceful shutdown cleanup logic |
-
-Exit codes are defined in `src/hooks.server.js` and are emitted when the process receives termination signals or encounters runtime errors.
