"""The individual rendered sections of the status window.

Split out of :mod:`screen_locker.status_view` to keep every file under the
250-line cap. Composed into ``StatusWindow`` there, alongside the other view
mixins, so the class's public surface is unchanged.

Every method here is display-only: it reads the snapshot it is handed and
paints widgets. Nothing in this module writes to disk or reaches the network.
