Drive the OEM first-boot keyboard picker to English (UK) and assert the
installed system ends up with KEYMAP=uk and XKBLAYOUT=gb — proving the
deferred keyboard step actually applied a layout, not just rendered. UK keeps
every letter identical to US so the raw-keycode password still matches, and
the email's '@' (Shift+' under UK, not Shift+2) is typed with the UK keycode.
The console bootstrap now fetches-then-runs instead of piping, so it survives
the non-US layout the keyboard step installs.
