Default: `~/.config/lolcathost/config.yaml`
The configuration is stored at `/etc/lolcathost/config.yaml` and managed by the daemon.
- **TUI/CLI changes**: All changes made through the TUI or CLI are automatically saved to this file
- **Manual editing**: To edit manually, use `sudo nano /etc/lolcathost/config.yaml` (changes are picked up automatically via hot-reload)
