  <!--
    v5c: Preferences, against Settings-Preferences.dc.html — the old PreferencesScreen.axaml's real content,
    restyled into the settings page idiom and split across two pages rather than one.

    THIS MACHINE moved to the Security page whole: Windows Hello's register/"stop unlocking here" pair and
    the no-TPM explanation are Security's UNLOCKING card now, one home rather than two — see the cross-
    reference row at the foot of this page. Device name is not one of the rows that moved; it never existed
    here at all, because there is no device-name setting to move. Logs record the machine name on their own.

    TERMINAL keeps its one real setting, text size, and drops the design's other five — font, cursor,
    scrollback, copy on select, terminal bell — which the renderer hard-codes. KEYCHAIN keeps Lock now,
    Sync now/Sign in, and the importer rows; the design's own SECURITY card (clipboard-clear delay,
    confirm-run-on-insert) has nothing behind either row and is not drawn here.

    Two importer rows now rather than the one the old screen had: ~/.ssh/config, and a Hetzner Cloud project.
