+Both required files must be present or the installer falls back to the configurator. `user_configuration.json` may set `omarchy_install.region` to `global` (the default) or `china`, the region the configurator asks for on its first screen. Generate the password hash for `user_credentials.json` with `openssl passwd -6 "yourpassword"`.
 
 Encryption itself is configured by the `disk_encryption` block inside `user_configuration.json` — which carries the passphrase in plaintext, so treat a drive built from an encrypted install accordingly. The flag file must match it: it drives the encrypted install's SDDM autologin and the final boot validation, not the encryption.
