The normal install flow returns to its original order: keyboard, then the user step, then disk selection and mode. The Ctrl+C shortcut on the first screen and its confirmation now speak only of preparing the machine for another owner — no 'OEM' in any user-facing string (the omarchy_install.oem data contract is unchanged).
